Anybody every play with or run a 576 head

There’s proof that everyone should not touch porting burrs. I think we have all done some type of porting work we shouldn’t have but he hit every base on that job.

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!
