Hi Guys
I have some of these heads GMMP LS3 6 bolt heads
Part #19201805

I want to fit shaft rockers like my old engine , I had T&Ds in a LS1 .

Does anyone know who makes rockers to fit these heads ?

The standard Ls3 T&Ds don't work on them . They don't use the base plate like standard LS3 heads do , They have the base plate casted into them from factory ,( if that makes sense ?)

These are going on a LSX 427 Turbo setup .

Also is it worth Porting them , Or are they good enough from factory for a Turbo setup?

Thanks .

You may have to mill the bosses down and run T&D's.

I though about that, But because they have 260cc intack ports they protrud into that area that needs to be milled .

Anyone else have experience with these heads ?
