L92 heads swap? There are a couple of you guys who are very knowledgable with engines on this board so i thought i would post this up.
i have a C5R 427ci, forged everything.
Got a guy who is interested in swapping heads with me. He has a set of ported L92 heads (350cfm @.600) but they don't fit his stock cubed motor. he is looking for an ls6 setup and was interested in mine. i have ported ls6 heads, they flowed 330cfm @ .614 so pretty good for stock heads.
anyways, i would gain a lil compression advantage lowering it down into the mid 10s. i'd throw thick gaskets in and then i "should" be good to roll for boost.
I would need to sell my FAST 90 setup and buy an LS3 intake. that should not be a problem. i can still use my Nick Williams throttle body so that will be nice.
Anybody have experience with the L92 setup? any info you know? i'd expect to gain a lil bit of power but the main focus here is lowering the CR to run boost.
thoughts? thanks guys!

thanks man. my current 243 heads were ported to the max. my current cr is 11.8:1. quite high for boost. i plan on running around 10# or as much as i safely can. my goal for this motor is 750+rwhp.
or...nitrous always can do the trick, but i want reliable, ALL the time power without issue.
