It didn't sound that bad. It all busted loose coming out of the burnout, the starter didn't hear it I shut the car off and told them to send the other car down the track. I thought it had broke a rocker.Believe it or not the short block can be saved, a sleeve in the block and 1 piston.
I think the B1-BS head would probably be fine with the 499 but I don't know if it would give me a lot of room to grow. If I had a unlimited budget I would buy 2 sets of heads, the B1-BS heads for my 470 short block and a set of 440-1s or possibly a set of ported Victors for the 499. Unfortunaetly I don't have that option, I am going to be stuck with the heads I buy for awhile. Decisions decisions.
