Edelbrock gets my vote as well. I went 11.50s with out of the box edelbrocks on a solid roller 11:1 360@3500lbs. I bought the heads, took them to the machine shop and had the valve job and guide tightness checked. Then I slapped on some springs to go with my cam and went racing. I later had Shady Dell to his stage II port job and install 2.05 intake valves. It went a best of 11.16@119.5. I just sold them to a member here, I almost didn't want to let them go they served me so well haha, the money is going to finish my Dana 60 and convert my tunnel ram to EFI though haha.
