78mm will work fine, specially since you won't be leaving much on the table with that cam. What TB are you going to use?

Are your heads 243 castings? Did he mill them any?

You will be VERY happy with the engine when you are done!

I had been looking for a fast 78 T/B but have gotten stock ported- bump stop mod ect , yes they are 243 casting CNC by Livernois in Detroit dont believe they are milled so stock compression. was seriously going to get TSP 5.3 CNC until the deal on these came up- 1100 shipped -I couldnt pass them up
