If you had to choose one, I would pic the one with the 326V8. It's hard to find a good OHC builder and parts may be harder to come by. There are some known OHC builders but none that I know of in your area unless your willing to ship it. The 326V8 interchanges with many Pontiac V8 parts.
No problem being a newbie. Everyone was one once. If you stick around, you'll be helping others before you know it.
