From their published flow #'s there might not be much work to do to them, but you never know. I stopped by after work today and I see he has a lot of new heads there to compare out of the box #'s to. New World Merlin, EQ320's, Dart 345's, Brodix SR-20's (F'n Huge!), some new Wieand tunnel rams and an Edelbrock single for the SR-20's. I'll stop by over the weekend and hopefully take a peak at your heads.
Rookie they showed up at Jims house rather than shop but he did a quick inspection and he said the runner looked a bit biggger then advertised. Regardless you'll probably see them before I so just keep me posted.

Jim said casting looked great. He did a quick flow out of the box with a 2.25 intake and was 382. Exhaust was 250. Both were flowed at .700.

Forgot to mention the exhaust was all done @ .600 but that's going to change drastically.
