I used the TFS street 2.02/1.60.
Normally, my die grinder starts warming up all by itself when I put a set of bare heads on the bench.
I took the TFS's out of the box, looked them over, and bolted them on to the motor. Didn't touch 'em. There's more you can do to the 351, but porting these new aluminum heads doesn't seem necessary. Spend xtra $$ on roller cam and rocker arms.
Spend your money on your sidepipes so the heads can breathe.
