    Default L98 Heads

    Will L98 heads fit onto an LS1?
    Will i have any problems with LS1 headers fitting onto the L98 heads?
    Will piston to valve clearance change?

    and

    Im guessing i would have to use a L98 intake manifold?

    Anything else i have to take into consideration??

    cheers

    If they're a cathedral port head I'm pretty sure they'll fit.
    I've never tried but thats what I've been told.

    Got me stuffed lol. I don't claim to be an expert on these things.

    I've just been told that anything with a Cathedral port head will be interchangable.

    I asked the same question last year.

    No the l98 head will be no good on the 3.9" bore of the ls1 you need at least a 4" bore to use the l98.
    Just get your 241 heads cnc ported and a set of stainless valves put in and double springs then port an ls6 intake if you cant afford something better.

    ^^ I had it on for a few months and then changed to LSXr102 set-up but they both work very well, Getting 350rwkws on E85 with stage 2 cnc 241 heads.
