360 build !help!
Pick an approach and stick with it. :)
If it's going to be a stock low compression piston, advance the cam to get some cyl pressure and low end. It's not hard to get 400hp from a 360 now days.
There are some decent options if going to aftermarket heads, RHS X's/ede/pro comp are the least expensive of the LA family. Mildly porting the factory heads can work really well too.
I agree on a shorter duration cam, cut it on a narrower CL and install it advanced to get some grunt if a street car.
The tune up, initial timing, curve and total will make a HUGE difference in how a car runs at idle.
I wouldn't wait for the Victors. I think they may be a good head... BUT, they screwed up on the exhaust pattern... W5... WTF
