512 Stroker

The reason I'm not going with aluminum heads, at least for now is $$$. If I want more HP, I can always buy a set and different cam. I've had these heads just sitting aroun for years...might as well use em. Several years ago, the heads were in a friends 68 fastback barracuda, with the exact same valves. Solid rockers. Battleship springs and the barracuda ran 10.20 in the quarter mile. I think they'll be good enough for me.
