    Default oringin, receiver grooves and studs? lil advise needed

    alright fellas im bout to tear down my all alum ls motor and id really like to do all thats possible now to seal off the combustion chambers as tight as possible, i plan on some majorrrr boost with this motor and its only got 4 headbolts per chamber sealing it along with factory mls gaskets. studding is necessary of course, already have those, but you guys think having receiver grooves put in the heads and oringing the block will help much? when i say big boost, id really like to be runnin in the 30+ range, fully plan on building the shortblock to handle it.
    the issue im trying to overcome is ive read countless threads on ls1 sites stating guys are pushing coolant at 20lbs on these engines with stocker heads. sure i could buy a set of aftermarket heads for it, but its a truely pointless expense when the stocker heads flow nuff to hit the power level im after, so i'd like to stay stock there, plus they're only 200bucks each used. heads are getting ferrea super alloys of course.
    i still have my cast blocked basically stock motor i finished up last spring, ill keep it for a spare, its jus too tempting to lose another 60lbs and have a longblock that weighs in at 325lbs ya know be fun to build a 900hp/ftlb sbc that weighs 420lbs built with the turb kit and all on it it'll put my boat weight in race form to around 1100ish

    so what yall think? oring and receiver groove the alum block and still use the mls, or go to titan ics coppers with the combustion seals? had good luck with em in the big turb motor.

    Dare to be different, if it turns out great you can claim you planned it that way.

    All you have to do is bring the block, copper gaskets and heads here.

    may do it ron, i know i can trust yalls work! so you're thinking copper/orings/receiver grooves ? i dont see any other way to keep the cylinder pressure in it otherwise we're basically gna build 2 of the same longblocks, but mine will be alum blocked, bill's cast(i gave him a longblock). give us a good reason to come visit and shoot the shit this winter

    Impai, this guy blocks off the water jacket holes in the block and heads, reruns the water systems and puts the boost to the moon. Of course he o-rings the thing but it seems to be very dependable. I know it's a drag car and a ford but for 283 inches it hauls the hay.
    Need help finding this 1973 Sanger 18'6" bubble deck mahogany bottom and stringers I was living in Pomona when I sold her in 1979. Just wonder if she still exists

    Update Found my old Sanger 12/7/14 in Reno.

    he's got more headbolts than me tho the turb i had spec built for my ls motor is capable of making 140lbs(roughly 1400hp) and i really wanna run bout 32-35lbs of boost to my lil motors, make em screammmmm

That's like the 20th time he's gone by today?"

    Your catching on If the thing takes a dinger with that kind of boost, chances are there won't be anything worth saving anyways.

    mark has been runnin his big turb engine without orings for yrs and yrs, wonder if it'd work better to have the block deck milled a cunthair except the sleeve area? his holds back pressure great that way cuz his cylinders are slightly highr than the deck surface.

    gna have to post that question on the ls1 site, gotta be someone doin it already over there.

    yep, prob right lol. we're gonna be runnin stock cranks in these things too with good rods and pistons, too many ls guys doin it over 1000hp at the track for me not to try the same in a boat.my junkyard dog ls engine i built will be there for backup regardless

    Yea but he kept pushing the head gasket out until he pluged those holes. Just a thought

    that's why i keep coming back to oringin the blocks and putting receiver grooves in the heads. lotta guys do the orings but not the heads like it should be done, then go and push coolant wondering how its possible when they had the block ringed the receiver grooves in the heads will have copper pushed into them which shouldnt let the gasket move at all, that's the theory anyways, jus hope its true on these ls motors got too much sunk into this now to turn back to bbc's my turb system is done, ready to run, but im leaving sooo much hp/tq on the table by not using the turb to its full potential, and knowing that would eat at me all next summer lol. plan is to tune the set-up on my cast iron blocked motor, make it work great, then jus switch out longblocks and crank up the boost

    Sorry I didn't make that clear. He already o-ringed the head with receiver groves in the block/ cylinders. Blocking the water holes let him use the full surface of the block and made it harder to push the gasket out. When I look at that little block, little main bolts etc and wonder how the heck it holds the power he is making.
