What FE rockers needed?

[Robin Maroney]

C4AE 6090G heads, What rocker arm stands required for these heads? Med riser or High riser? Will a RPM performer work? or will I need to use a 427 high-riser type port intake?

Those are standard passenger car lowriser heads.  You could yank the valvetrain off any factory 352, 360, 390, 410, or 428 and slap it on there.  A Performer RPM fits just fine.  People like them because they have a larger intake port, but they're still lowriser heads.

Thanks for the info

We are running those same heads on our 445. Just FYI we had to raise the stands 110 thousandth to get rocker geometry correct.
