Are there any spark plug clearance problems with Edelbrock 5090 heads with the angled plugs using old Heddman 1-5/8" headers? I've heard stock manifolds can have an issue.
Which way are the plugs angled? I guess I can take a look at my motor. I know a couple plug wires are pretty close to the headers now. From the picture, it just looks like the two center plugs are angled outwards & the outer plugs are straight.
Also, I think I "heard" their single valve springs were junk??? I'll be running a mild street cam, maybe a Comp Cams XE274 or similar & stock valve gear.
Anything else I should know about these heads before I buy them?
