Thanks Topless69, your comments kinda sum up all the replies to my initial questions and are very useful. I do have a good running stock 1972 318, which has an advertised 8.8:1 static compression. I was planning on using Mr Gasket 0.028” head gaskets and milling my 920 heads to achieve around 9.2:1 comp, or a little more.
I have a Comp XE262H cam, an Edelbrock Performer intake, an AVS2 650cfm carb, and a set of 1-5/8” long tube headers. If I open up the bowls & port match the heads and intake manifold, get a good multi-angle valve job, I’m hoping this will make for a way better street only combo with the 4 speed and 3.23 geared rear.
The only real issue I have is that I like the way the car sits now, so I may just port match the exhaust headers and call it a day. The Flowtech headers I have will sit too low. I may look at getting a set of Doug’s 1-5/8” headers that appear to fit better.
