Another low budget 360 build

I want to thank for all of the help with this project. Didn't think it would take so much more thought lol.
Think I will stay with the current plan of H405CP, go with the 60402 cam, 901-16 springs.
Check into going to 2.02 on the intake valves and shaving a little more off the heads.
Would it help any to advance the cam 4 or keep at 0
