Well now I've got an offer for a pre-prepped head from DH-Racing This includes worked over milled valve jobbed swirl polished valve and assembled with springs.

He's also got a custom cam that he would sell to me. So with this stuff, what kind of tuning do I need if any? Do I need a cam gear? I'm still waiting for him to reply to me about these questions so we'll see how it goes. So as of right now, if I get this head then I won't have to get the current one machined which should bring down the cost significantly no?

What kind of gains can my friend expect with this along her Fake J's intake, DC 2pc header, RT high flow cat and 2.25 piping with a baffled muffler?TIA
