Thread: Brodix IK Heads.

Yep, 0.044" squish/quench will work fine for use with pump gas Dean, although 9.5:1 SCR and 7.8:1 DCR are very conservative numbers for use with aluminum heads.
What's your piston crown configuration or piston part number, head gasket part number and cam part number that you will use? I'd like to figure the SCR and DCR just to make sure for you, if you don't mind. You have several thousand dollars at stake and I'd hate to see you leave power on the table that could be picked up easily at no additional cost using the 70cc heads instead of the 72's and maybe a little different cam. The 185cc intake runners will work great with your 357 cubic inch motor.

Hi Tech, this is what i have so far.

350 bored .040
Flat top pistons 4 valve +5.00
piston to deck height .005
Lunati 270/278 Hydraulic roller, @50 219/227 515/530
Head gasket .036 thick-- 4.165 bore
Edelbrock performer intake
street demon 625

Was thinking to keep around 9.5:1 for my cam size, and to keep header heat down a little.
