Would a switch to aluminum heads allowed you to keep running the 38 degrees of timing and resulted in even more of a power jump?
This is interesting. I would like to have expanded on this even further.
What if I had preserved the comp ratio @ 9.4 with a -.055" deck vs. a 9.4 comp ratio @ zero deck? I believe the difference would have been more on the order of 1.5-2%--maybe less!
To answer your question--first I don't have an answer I have never done this. Second--I doubt it. Aluminum heads are not some magical engine parts. I'm not going to explain it here but --think of excessive advance as "negative torque" or not getting the job done as "fast burn" stuff. J.Rob
