The heads are stock square port which I am planning on getting ported and polished. I found someone in the are that has a flow bench. The cam is a roller which I had in my 540 I still need to find the spec sheets on it.

Dyno, do you have to use 92 octane all of the time with that 9.6 to 1? I forgot, are you using aluminum heads? Just curious. It's hard to get good premium on the water sometimes.

No, he can run 89 octane without changing timing, which is set at 32.
