Help with 340 compression + cam change

This has been a great thread and I wanted to thank everyone who contributed!!!

I am pretty clear as to what direction I need to take. When I get to tearing the 340 down some, I'll find out exactly where the pistons sit, change the cam, change to some better springs, and at least put the thinner head gaskets in.

For now I am dialing in the new 650 AVS2, AF meter and seat of the pants tells me I'm real close.

I live 20 miles from Heartland Park in Topeka and they are open for the Friday nite test n tune sessions, so I'll play a bit more with timing and fuel first.

Again, thanks all!!!
