TPI Intake Capability with Various Chevy Heads
*I'm looking for a source that identifies the compatibility of 350cid TPI intakes with the various 350 heads available for late-model Chevy V8's. It's my understanding that TPI set-up's aren't fully compatible with all 350 heads.
Reason: I possess a TPI intake from an '89 Corvette and am currently investigating a TPI-equipped crate motor set-up for a '90 IROC-Z.

The Corvette TPI intake has the perimeter-bolt-head intake pattern, with all 45º holes. The 85-86 F-body intake is the same. The 87+ TPI intake has the centerbolt-head intake pattern, with the middle 4 bolt holes being 72º. Just match up the head angles with the intake angles and you'll be fine.
