If you can find some splayed valve stuff from someone you can trust it will be impressive on the bigger inch engine. Minimal driving and a roller , I would not be too worried. You cant get on the power of a splayed valve or even a SB2 head. There used to be some good deals on used SB2 nascar heads complete. Just something to think about, it way cost some more but there are great deals on the used small block stuff that will make alot of power. If you want a cast intake on the splayed valve head you can get a Chrysler intake to work. LOL just grind off the penta star.
