Anybody every play with or run a 576 head

That's me!

I have a set of clean 576 heads if anyone is interested in seeing more pics. Have the "308" porting templates too but don't worry John, I have not broken out the burrs on these yet!View attachment 1715543272 View attachment 1715543273 View attachment 1715543274 View attachment 1715543275 View attachment 1715543276

Whatever you do, do not make the exhaust port bigger. It’s too big to start with and the shape is horrible. Take the bump out of the roof, and remove the smog bump if there is one and do your best to get something like a radius on the short turn.
