Engine - 357w

Carb - Holley 800cfm

Intake - Edelbrock Victor Jr. (3,500-7,500rpm)

Cam - Lunati 51012, Hydraulic roller tappet, Duration at 050 inch Lift: 232 int./242 exh, Valve Lift: 0.544 int./0.560 exh. 112 Lobe center! (2,800 to 6,500rpm)

***HELP*** Heads: AFR 185cc's (1,500-6,500rpm)? or AFR 205cc's (3,500-8000rpm)? which one would work better for a pump gas street/strip build, wanna try and hit a 12 flat/squeeze in a 11. 1/4 mile wise.

I think the 185's are a better choice but on Air Flow Reaserch website they say "non-emission legal 185's" or "emission legal 185's" and I live in canada we dont have emissions here so what are they both the same head and everything but whats changed, i really need this explained.

I noticed the non-emission legal 185s have a nitrous exhaust port option, and i will be using nitrous eventually.

Last thing whats the price tag on these AFR 185's? $2000 approx?
