Hey guys, I want to put the Holley Stealth Ram on My ZZ4 motor. Will it bolt to the ZZ4 heads fine? I know when i installed my stock TPI intake onto the ZZ4 heads there was an issue with the center bolts. I had to elongate the center intake holes to make it mate up with the ZZ4 heads. I did a search on this and all I could find is what I have listed below. Are the ZZ4 heads considered Vortech?? I know I sound like a newbie here, but I have been in and out of this group for years. I moved, and couldn't remember my old email address that I signed up in here with, or my user name or password, so i had to re-register, which really sucks. Below is waht I found in a search. I just do not want to get the Holley Stealth ram, and have to elongate the intake.
Thanks!
Mike

The Stealthram is drilled for both early and late model SBC heads so it should fit most applications except Vortec. However, the ports are designed for a Felpro 1205 gasket. Larger ports will not fit.

Q) Does the Stealthram work with late model Vortec heads?

A) No.
