3 angle or 5 angle
Ok so I turned my TSP stage 1.5 heads over to a machinist today....I bought them with 20k miles on them but wanted to have them disassebled, cleaned, pressure tested and possibly have a 5 angle valve job done on them....the standard seems to be a 3 angle....would a 5 angle be better for my twin turbo forged 402 setup or is it a waste of money?

The way I understand it, the 5 angle job will have smaller faces on each cut and will wear more quickly. The 3 angle job is the standard and is plenty good enough. It should last longer. If you're trying to get more power, turn the boost up another 1/4lb and save your money.
