    New Heads

    gonna be getting heads soon......these are what im looking at:
    http://www.jegs.com/p/AFR/756111/10002/-1/11183

    question one.....for the extra $200 is it worth it to go w/ the .650 lift??? And what would those bring compression down to???

    question two......where is the best place to get the center-bolt valve covers from??? and can i get just the coil rack???

    I have a 98......so the coils are bolted directly to the valve cover....i assume they can be bolted directly to the rack thats on the '99 and up....but please correct me if i am wrong.....

    thanks for the help,
    Andrew

    -still more to come!!!!!!

    AFR makes awesome heads, get them milled to bump your compression.

    I have a set of valve covers, PM me if you end up needing them.

    You dont need 650 lift springs with an LS6 cam.

    you dont need anything over .650 lift, as it is extreme overkill for a street application. personally if i were you, i'd get the .650 lift springs for peace of mind so in the future if you choose to run a cam over .600 lift you wont need to upgrade the springs...

    that's fine. i have heads with springs rated to .650 lift and my cam is .581 lift. if i step up to a cam that has over a .600 lift im good to go with just a direct cam swap...

    I mean, valve sprgings should be changed at 15-18K miles anyway if you have an aftermarket cam, so it's not anyone is bound to anything for life here...
