You might be able to get away with more compression. I don't know the engine build specs, they must be in the other thread? Anyway, my 468ci. small block in my car is 13.3:1 compression with a cast iron head, and I run it on pump gas, and a meth kit. The meth kit is kind of for insurance. I have made passes on straight pump gas. BUT its a big cam, somewhat short rod, and a big crank. Each build if different from the next, but that is my experience with my car. Most of our customer cars on pump gas are going out the door at 12-13:1 compression these days.

With the cylinder pressure not being that bad with the huge cam I know the compression could have been 12.5:1 and safe. But didn't wanna change the pistons or deck the **** out of the heads for a good reason down the road...

They are custom made stainless 2" primaries with 4" collectors. Didn't see any off the shelf headers I liked even the Kooks F-Body ones so I had them made.
You need a set! Actually larger primaries but that would help a lot.
