Question ETP L92 Heads for 3.9" bore
Craig, Cary whatever happened to these heads?

I last heard that the ETP L92's were coming out in October, but I guess not.

Any new info?

I'm still wondering what's going on with them. I've got to plan my camaro's motor out. I hate it when you just finish something and then something newer / better comes out.

No ****, man; I hear you. I call that the "2004 GTO Effect."

This is the first I've heard of them. My motor's coming out and I thinkI'm getting ready to replace it with a budget 346 shortblock, some stock LS2 heads, and a cam package.

L92s will not fit a 3.9 bore of a 346ci
