Rebuilt 302 casting heads available through Rockauto

Mike,
You've got 2 cores worth $100 to Rock Auto, when they get more in. Do you want to work on your own heads? You could still take their rebuilt ones apart to port them or whatever.

I haven't taken mine apart but I bet they could use some valves. They came out of a good running 5th. Avenue but it had 100,000 rounds on it and not well cared for. Teen heads work well with larger valves and with different guides you can use Magnum valves. (smaller stems) I would have Woody port them like he did my 273 heads.
