Re-building head

[DSMMER06]

Im rebuilding 420a head soon with crane turbo cams and crane titanium valve springs and retaianers. I plan on getting it ported and polished...what would anyone else recommend?

3 or 5angle valve grind, and a ported stock intake manifold with a 60mm modernperformance TB if you really want to make it all worth wild.

The TB can wait, but if your having them do the head, might as well have them do the intake manifold.

^^Yup, The 5 angle I kinda like, given the choice. Just a little insurance that my machinist charges me very little for.

Also, in all my rebuilds I use stainless valves. Just a little more durable.

High recommendation to get rid of those injector humps in the intake.

Side note to Randy; You knew going in that it would be hit or miss with CI. My condolences and good luck with that,

Yeah I know its been a while since I ordered from a place that I didn't know the person at the shop or knew of someone who knew them personally, and I wanted to support a dsm vendor (with 5billion stars next to their name).

They were really cool when I started the order, communication was great. Then I was told it was being processed, and then complete, and when I emailed them to find out what that means, I didn't get a response....anyways enough complaining (mods delete this later)

Yeah your going to want to knife edge those injector ports.
