383 in work...slowly, but in work

So, I hate you guys....not really, but after reading a BUNCH of posts about big blocks with solid cams, I'm starting to lean that way. The purpose of the car hasn't changed really...I still plan on having it as a weekly cruiser, maybe some strip time. I bought the 915s off eBay and still want to put bigger valves in them with some mild porting, but again, the more I read, the more my eyes are shifting toward a set of Stealth heads prepped by one of the gurus on here, or a set of Edelbrock E street heads with some seat cleaning.

I have the old school adjustable ductile rockers, and a set of springs-pretty sure I scored those from physixx a few months ago-not sure on the numbers on them, but they're doubles with a damper, so I'm gonna make a WAG they can support some bigger cams.

Any ideas for recommended solid grind, y'all?
