I'm no expert but if your tiger head peaks power anything like a Ehead (I have no clue) which for mine is 34-35 degree's. That would be 10 degrees you took out right? I have a 461 ci with a 150 shot . I don't take out anything . I do take out 4 degrees with a 210 shot though ... Doesn't sound that far off to me. Are you certain your A/F is correct n/a? Do you free flow your regulator to your nitrous jet to 5 psi? Im just sayin, maybe it could be something else then timing?
How do the piston lands/rings look?
