Are Tiger heads too soft for boost?
I have had terrible luck with nitrous and this tiger headed 537. The heads actually started to go concave at the center ports and I resurfaced them 3 times. This time we had to go .010 cut. I was using .060 cometics this last time and pulled 20* timing for only a 200 shot and still torched the block and head. I am selling all the nitrous stuff and putting on my F-2 Procharger, my question is, will these heads work with about 10-15 lbs. boost?
