    i understand the company was liquidated, equipment sold.there are sets on ebay now from someone liquidating the canfield inventory,both bare castings and ported bare castings.prices seem very resonable for american castings and machining. dont know history of canfield but these heads have raised exhaust port i think 5/8" up.

    I ran a set on a twin turbo 496 last season and they worked great!!! 16lbs of boost on 92 oct pump gas pulled a 9.5 high helix AAA impeller to 6500 with that tune up.

    Can's have very strong ex ports that can easily go over 300cfm.. They also have relatively large X sectional areas on the intakes...far bigger than most would think, or need. Really too big for most small (under 500) na engines. With the 2.25 valve, the restriction ends up being in the valve area wich is really counter productive to making good power. The Can 310, with a 2.300 intake is sized ideally for a 7000rpm 540 na. I may be doing a set here soon that we can really see wht we can get out of them. My guess is they will go in the high 380's. I've gotten 370+ from the 2.25 intake (@ .700")

    That's right in there for that size head. Probably worked real well.

    X2 with what GN said. For the money you can't go wrong with them.
    Their ports have some peculiarities, but they do work well. What I like most is the chamber design. Seems to work very well. Hopefully the new genertion head will be even better, although I don't believe theylre going to be the "bargain" they once were.
    Steelcomp, the new generation will be priced very competitive. The goal is to make them better than before, but not break the bank.

    Trying to find the flow numbers.. Only have my Pontiacs and Olds.

    We just like the Toplines more at the time along with my oldman being able to get them at a really good price. Out of the box they were a better head it seemed also. The one thing I did like about the Can's was they had different combustion chamber sizes available compared to only a 119cc from RHS/Pro Topline..
