As others have said cams. Mod-S or wilder.

10.5:1 is alright if you don't mind buying race gas but keep in mind that means no long trips unless you want to carry extra race gas with you.

The 3.0 rod bolts are supposed to be very robust. I believe your weaker link from an over-rev is the valve springs. I'd save the money on the rod bolts and put it toward stronger springs.

I would talk to John Dougherty before you port the heads. The cam decision should be the determining factor for your ports.
