Hello, Im in need of some help choosing parts for my 79 ford 302 engine going in for 92 ford flareside.

Mods to date are: long tube headers, dual exhaust, performer intake, 600cfm carb, and ported 79 heads.. it has a 4 speed std trans, 4.10 gears and 33" tires.

My question is about a good cam and heads for my setup. I have been looking at GT40 heads, and a Isky 270 Mega Cam. Does anyone agree with my choice or am I way off for what i want to accomplish of a truck with some power, and a nice sound idle.

Any better combo I should be going with?

thanks
