'308' -casting heads

The issue with hogging anything out is the possible cracking of the head. A good machinest/head porter will have it magnifluxed first and carefully port the head.

Though, this is no guarrente (sp) of anything turning out perfect, at least the proper steps are first taken before any real money is dumped into the head.

The 308 has the best ports of any pre magnum head and should do very very well in your build. I'll be honest though, I do not think you'll need them ported in any form.
