So my combo is as follows ZZ4 short block with AFR 195 Street head and Comp Cam 08-433 cam with Edelbrock RPM Air Gap intake. 780cfm ProSystem carb. 1.6 Comp rockers. Full MSD ignition Digital 6 box dizzy and all. I was think of angle milling my heads to boost up compression to 10.8 to 11.2. Do you guys think it is possible to safely remove enough material from the heads? I would also do a valve job at the same time what would you recommend? Does anyone know of a shop or person in the Metro Detroit, lower Michigan or upper Ohio area that they would recommend for the work? Do I need special intake gasket, if so what FelPro part number? Thanks in advance. Cam spec. Intake Duration at 050 inch Lift:236

Exhaust Duration at 050 inch Lift:242

Duration at 050 inch Lift:236 int./242 exh.

Advertised Intake Duration:288

Advertised Exhaust Duration:294

Advertised Duration:288 int./294 exh.

Intake Valve Lift with Factory Rocker Arm Ratio:0.520 in.

Exhaust Valve Lift with Factory Rocker Arm Ratio:0.540 in.

Valve Lift with Factory Rocker Arm Ratio:0.520 int./0.540 exh.

Lobe Separation (degrees):110

I know we have angle milled bowtie heads .175, so I'm sure you can do the AFR's. One of the guys here will know how much. Also, tell your machinist to mill the intake side to match, and then use any intake, and normal gaskets.
