Ditto on the HEI, the jury is out on the 194 head, TLowe ran some dyno tests this year that show that's more of an urban myth as far as making more power, the port lumps will help build power and if you get the manifolod from Langdons you can order it with the water plate and the casting bungs are welded in and won't leak. With the cast headers the exhaust rap will make you sound faster and sound a lot kooler than a bent 8.
