Are the locks and retainers identical? If they are, this is likely a take off from the base single springEd twister wedge head and not the kit for e7 heads with differing valve tip lengths between intake and exhaust.

Ahhh I see Rob. The springs came with the twisted wedge heads that I had purchased, so that is the most likely case. Thank you for the information.

so this is a no go on e7 heads?
I dont believe that you'll have to machine the heads. But as Rob stated, since these are a take off twisted wedge heads, the installed height won't be correct for the e7 heads. So you would need to either get different locks or shim the rocker arms.
