383 big block builds, from mild to wild, I want to hear about them!!

1969 formula s 383 four speed, I am building to exact stock replacement, trying to keep the compression up at least 9:5 to 1. hard to do with new .030 over KB162 383 pistons, 915 closed chambered heads and .019 steel gaskets, and comp cam version of the 335 HP engine. But, it will be whatever it will be.The car is a bone stock original 70k actual miles, no previous accidents, or body damage ever. Hopefully by July it will run!
