Thanks Greg... The cam you see on the table is the one out of the 604 crate...it came with the heads. My original intention was to build my engine into a SP383 which uses the larger cam, and if I decide I'll buy that cam instead ($275). My bottom end is identical to the SP383.

I am not an engine builder although I have put a few together back in the day. Part of my thought process here is to make this as easy as it can be to put together a parts list that all works perfectly together the first time. The SP383 uses the same 1.5 rockers, same pushrods, same lifters, so I'm assuming that all of the valve train geometry will work as designed should I use all of those same parts again. I'll double check it for sure...but that is the plan. I actually have a set of 1.6 GM rockers that I picked up to use on my current heads...so that is an option also, but from everything i read the 1.5s work great with either cam.

I've read that the Fastburn heads work great right out of the box and I knew if I used them, I'd be able to emulate the rest of the parts the SP383 uses and put a good engine together the first time. My one main difference is the use of a dual plane intake vs the single plane. I guess that is my question, how should using a dual plane intake affect my cam choice given this scenario?
