SM Head Install... forgetting anything?
@pittsburghracer these heads will be great, hopefully, as I've never personally ran them. Tony, 70aarcuda on FABO, has many sets and has nothing but good things to say about them. For 1100 bucks fully dressed on black friday makes them even better. He gets them bare and add his own parts to them, I seem to recall that he doesnt like the springs. I bet you could plug and move out the bolt holes, but I can't guarantee it
