I think I did a bad thing.... I left my pride and joy legal Super Stock aluminum cylinder heads on my primary race motor with studs on for 5 years.... I spent all day trying to remove the heads. I just hope the damage from pounding, prying, and beating can be repaired. The motor has been all over during the last couple of years. Salt water, fresh water, Firebird water (the worst). This could cast a showdow on Laughlin 5-31, 6-1. I will see if someone can fix them in one week. Anyone have a pair I could borrow for one race ??? I know ... silly question.
