6 bolt crank is all you need but before you decide double check availability on flex plates. You'll want a high quality flex plate for that engine and sometimes 8 bolt ones are easier to find in the SFI grade. Head studs can be a nice upgrade but sometimes they'll interfere with the header flange. With the power you'll be making you need to upgrade a lot of the little parts. You'll need Cometic head gaskets for example, and the best bearings. The one piece rear main from Fast Fish is usually a good investment but you might want to talk to the engine builder before you buy too many parts. Some engine guys only want to use certain parts.
Yep, we did the 8 bolt Molnar crank. Competition Products had good pricing on the crank and rods, but that was quite a while ago. You might check them out, though.
