I am currently bolting my junk back together to go to MATS and want some opinions on Edelbrock heads compared to a set of moderately worked 915's. I have a set of Eddie's laying around and I am thinking of throwing them on my 440. Here is a short spec list, trw 2295's, 304/272@50-555" solid cam, and basic oiling system. The 915's had stock sized stainless valves and were basically cleaned up and gasket matched. I ran it with an M1 intake and a 950hp holley. What gain do you potentially see from the edelbrocks? I also have a victor I could put on as well. All opinions welcome
