Both sets are now cut. Thoses were measured originals. Since then, one has had a valve job and cleanup cut and the other new valves and a cleanup cut. Cuts were about 0.010". They now measure 77 and 78.

Anyone know what ACTUAL piston to deck is on a 67 440 ? I'd like to do some math to determine actual compression ratio vs. claimed.

And no NHRA spec Deck to piston is not correct .
