Hello everyone! I've built a 70 Challenger with a basically stock 383. Engine is .040, Purple cam, Edelbroch intake and carb. I believe 916 heads. I've been thinking about going with aluminum cyl heads. The stealth heads are considerably less money than other alumn heads I've priced. Why so much cheaper? I'm I just wasting money? Also, can the original style rockers and shafts be utilized? I really don't want to go too exotic! Thanks for any input on this! Take care, Jeff
