Need help, advice with my 318 build

Awesome build. Very similar to my build except I am going for a bit more performance 2000-6000 RPM.

Ok on the cam, it has a built in 4 degree advance to make up for low compression engines, so installing it 4 degrees retarded(from factory) or what would be center will help. It may help to go a tad bit further maybe 2 degrees. Torque won't suffer much and with all that compression may help you run without detonation. Look into that if you keep that cam for sure.

As for a cam change, I would look at the 700, 701, 702 Voodoo cams from Lunati. They all play into your plan to a certain extent but all(even the smallest) will have more cylinder pressure bleed off than the Comp you currently have. They also have 4 degree advance so the same rule applies on your new build(Good Compression/quench) with them as well.

Next your heads, I am no expert head porter or anything but from the one picture your work so far looks good to me. To keep the good port for torque, just don't mess with the floor too much. Pushrod pinch can be reduced a bit but for your goals you don't need much. I think the heads stock, with what you have done and a valve job should get you to your goal no problem.

I believe your plan is solid, don't get discouraged.
