Massive oil leaks.

Most of the complaints I've heard about the 440 Source heads were concerning the keepers on the valves. From what I've read you really need a competent person setting them up to make sure they're right. I think I'd ask the shop that repaired your problems to check them out for you.

I have the victor heads with 440source rockers. I have seen some negative stuff out there about the rockers blowing up. 2 mopar builders told me to yank the 440 offset rockers out. $300 rockers can't be worth a damn. I feel like I'm rolling the dice when I rev it. Would love for someone to tell me I have nothing to worry about.
