    Default Heads 408 sbc... RHS/Dart?

    I'm trying to get some heads for my 408 sbc(400 .40 over) and I told my builder i would supply the heads for him. Im on a budget for heads so no AFR and yes i know they are the best. My builder told me to get a aluminum 200cc intake and 64cc chamber head. So a buddy of mine said i should look at the RHS heads or the Dart SHP aluminum heads. He said both are great heads for the price, but he would lean more to the RHS.

    Any opinions?

    I have a Powerplay XLT185 Integra
    Alpha SS outdrive

    Right now I have flat tops, but I will be swapping those out with dished. Looking for a CR of 9.5-9.6.

    Just a heads up, RHS is no longer casting their heads in New Zealand, OR Australia, OR here. So I will let you figure out where they are coming from. They are also no longer selling iron heads for the same reason.

    I would go with either the Dart SHP, Edelbrocks E street, Brodix IK, or Trickflows if you are on a budget. Or see if you can find a good used set of heads. Thats alot of SBC stuff for sale out there.

    See the RHS over the exhaust port? That is no longer there on the newer RHS BBC head. Same with the SBC.



    This is a pic of their current head, and you can see that the logo over the exhaust is gone. It is now nothing more than the "copy" of the RHS head that has been peddled around for years now. The entire RHS line is like this.



    This how they now "ID" their heads. Its the same with all their heads. MMMMmmmmm



    JUST A HEADS UP TO LET YOU KNOW!

    You know... I started doing some more research and actually talked to a RHS rep, and he is saying that there head castings are done in New Zealand. They are then machined in Michigan and then sent to Memphis TN. He said it was total BS that they where done in China.

    WTF....

    Take it for what It's worth. You asked the question here and got an answer from a knowledgeable guy. If you want to go with RHS, go for it. There are plenty of SBC head options...

    There is a member on the boards here that did a set of newer RHS heads for a customer. They were bought BARE shipped straight out of Michigan, and they were in plain Jane brown box that had "Made in China" on the box. Not the pretty orange box you see below. My guess is they don't pushed into the pretty orange box when they arrive in Tennesse. When you see a set, it pretty obvious they are not the old ProTopline/RHS head. It just looks exactly like. But then, so did the "copy" heads that have flooded the market.
    The RHS head lost the logo over the exhaust at the same time that RHS stopped selling iron heads, ACROSS THE BOARD, none, nada, zero iron heads, for any engine. The iron heads WERE cast in New Zealand. They were also machined in New Zealand in the same plant that cast them. No different than Edelbrock here. Its called "vertical manufacturing" and it all takes place under one roof. That was a big selling point when ProTopline made them.
    Any desired changes needed in the casting was a few steps away to get done. When the heads were ProTopline, the logo was in the same exact spot as the RHS logo. Now its totally gone! Why change the tooling to get rid of that? So you could engrave it in the accessory mounting pad where it gets covered with crap when used in a car, and the other side is up against the fire wall? ReallY?
    It didn't take a rocket scientist to tell the difference between the RHS head and the "copy" a short while back. I wonder how RHS would feel about a direct comparison with their current head side by side in the office? BTW, the jerk that sells the "crap" head maintained for years that his heads were cast in New Zealand and or Australia for a long time because the route to the U.S. from China was thru Australia. They arrived here from Austrailia, looked like ProToplines. Who knew. It didn't take long to figure it out. They don't bother tryiing to bullshit anybody with that nonsense now.


    Interestingly, the iron heads that RHS did sell, are now being sold as EQ for both the BBC and SBC, and soon, the SBF. Same tooling. Cast in.....you guessed it, New Zealand!
    This is the "so called new" EQ BBC head. It is the same exact head RHS use to sell. If RHS was still getting their aluminum heads out of New Zealand, from the company that cast these iron heads, then why did RHS drop the iron head line? Make sense?
    I have seen these iron BBC heads, and they are NICE! 1200.00 a pair assembled, with pretty decend parts. 900.00 a set bare from the Manufacture. hard to beat the price for a head like this.



    I try as hard as possible to have as little dealings with Comp as possible. Dealing with the camshaft division is one thing. The offshoot businesses, no way! Like there is two different people running the show, because there is.
    I wouldn't trust a tech at RHS to have a clue where that stuff is made.

    Default TrickFlow

    I can't speak for the Darts, but I put a set of TrickFlow 180s, 62cc chambers on a .080-over 327. With Comp's Xtreme Energy 262 flat-tappet, 10:1, and the Holley StealthRam, it is so crisp that I had to change gears to make it drivable. Had 3.70s with a posi.

    With the 700R4 trans, it would literally light the tires as soon as you cracked the throttle. Switched to 3.36s and it was still too quick off the line. Ended up with 3.08 posi and it's just right. Of course, this is a STREET application, but this was my first set of aluminum heads and they just work REAL well. I am sure the Darts are every bit as good.

    So, I haven't had SBC heads THAT big (into the 200s) but I can tell you the small TFs work great in my application, right out of the box. I would also like to try one of Edelbrock's top-end packages. I've heard good things about their heads.

    The Trickflows are one of the most underestimated heads out there. Thats why I listed them in my post. The Edlelbrock E Street are probably the best bang for the buck, but the Trickflows do work. and they have up to a 230cc 23o head.

    Well, again, I can highly recommend the small ones for a street or smaller boat motor. Right out of the box they were sealed up nicely and measured 62.7 avg on the chambers. $899 for the set with 1.25" valves - again, small street motor. Bitchen heads.

    Just thought I would give you all an update... I ended up going with the Pro-Filer 195cc / 64 cc heads. I have herd alot feedback on these and been told they are the best performance for the money. Plus... Made in USA.

    Too bad you have already made up your mind. The Chevy Vortec head is a really nice peice right out of the box with a KB dished Hypereutectic piston. A killer peice for the money. Just my 2 cents. I have a 400 inch in my tow vehicle.
