SOLVED - Dart rep said FEL-PRO 1206 intake gaskets are what is required.

What cylinder heads are these and what FEL-PRO intake gaskets do I need for them?

383 SBC but the intake gaskets are leaking vacuum at the top of the intake runners on all cylinders by the valve covers.

Looking for the RIGHT intake gaskets for these.

 

Call Dart ask what intake gasket is needed for a SBC Iron Eagle 215 head.

Or measure the port height and width and search for a gasket that will fit your measurements.

 

According to the Summit website, the only 215 head Dart makes is aluminum, not cast iron.

 

Took your advice and called them up and asked about the heads. Discontinued 6+ years ago and take a Fel-Pro 1206 gasket.
