LQ4 build questions I'm building a new LQ4 for my rock bouncer. I want to run E85 or E98 and be around 14.1 compression.
The short block is
K1 4.00 crank
Molnar power adder rods
Carillo 4.045 10cc dome pistons.
For heads I bought a set of FED LS3 stage 1.5. I got the heads slightly used and was told they are .10 milled. Im still needing a cam and wondering if I should take another .20 off the heads. I'm new to putting together the LS motors but wanting to get the best bang for the buck. Or would I be better off selling the heads and buying another brand?

Right now with .010 off the heads and a .051 stock gasket you'll be around 13.7-13.9 ish depending on how high the pistons come out of the block. Using .007 in the compression calculator it comes out to 13.8
Personally I would stop there and have the extra .020 for PTV clearance
I think your heads will work great, typically you'd want a cathedral head for more low end (big port LS3 heads tend to drop off low end a bit) but with a 411 cube stroker motor and high compression I think it'll be a monster.
