Which engine?

Re: Which engine?
How much is a crate motor? How much is the claim? And do you swap engines for the claim or is it outright?
Since I'm really cheap when it comes to lower division circle track claimer engines, I'd probably find a good used core engine and run it as is after changing the cam and "freshening up" the heads. Use the right bowl cutter to open up the heads, being careful to reproduce the chatter marks and not going too far, then back cut the intake valves from 0.030-0.050 from the contact line on up at 22 degrees. On the exhaust side, it depends on the casting and you really need a flow bench to help you out. But the real gains are on the intake side.
Review this video for exhaust manifolds.

One more thing, the factory powdered metal rods are fine as is. That'll save you some money.
