excellent metal core graphite header gaskets - used many years by myself and others with thousands sold
Pontiac Exhaust header gaskets for all ROUND-Port Pontiac heads both iron and aluminum.
works great on headers and iron exhaust manifolds
Please verify your exhaust ports - the D shape is just the center ports AND UPRIGHT D - or mirror themselves
Many of the aluminum heads like Edelbrock are D shaped but mimick the round port Pontiac pattern
If all ports are D shaped and face down, you have round port heads !
pay attention to the pictures
