Pontiac V8 Cast Iron, Early Style 57-64, NON SD
Before the Change — Cast Iron, Early Style 57-64, NON SD for Pontiac V8s
This is the early cast iron intake gasket group — the 1957 through 1964 Pontiac V8s, before the intake face changed for 1965. It does not cover Super Duty engines, which use their own parts.
Butler stocks the two early patterns: a set for the 1957 347, 1958 370 and 1959-60 389, and sets from Fel-Pro and Best Gasket for the pre-1965 big-inch engines (except Super Duty) from 1961-64 and the 326 in 1963-64. Order by casting years, not by displacement alone.

More About Cast Iron, Early Style 57-64, NON SD
1. Two patterns inside one era
The early Pontiac V8 run is not one gasket. It splits again around 1961.
| 1957 347, 1958 370, 1959-60 389 | Butler stocks a Fel-Pro set cut for these engines. These are the oldest Pontiac V8s in the catalog and they do not share the later intake face. |
| Pre-1965, 1961-64 | a second pattern covering the big-inch engines of 1961-64, except Super Duty, and the 326 in 1963-64. Butler carries this set from both Fel-Pro and Best Gasket. |
| Not Super Duty | Super Duty engines are excluded from this group on purpose. They take their own gaskets, and the 389-421 Super Duty also uses a separate expansion plug in the heat crossover or intake center water hole. |
2. Why this matters when you buy an overhaul set
This is the single most useful thing to know about early Pontiac intake gaskets, and it catches people every year.
| Overhaul sets ship with the later gasket | Butler's Pontiac overhaul gasket sets include 1965-and-up stock intake gaskets. If your heads are 1961-64, the intake gaskets in the box will not be the ones you need. |
| Add the early set | Butler's own kit notes call out adding the 1961-64 intake gasket set for early heads. Order it at the same time as the overhaul set so the engine does not sit waiting for one gasket. |
| Check the heads, not the block | the intake gasket follows the cylinder head castings. A later head on an early block, or the reverse, changes which gasket you need. |
3. What to do before the manifold goes down
The early manifolds are heavy iron and the sealing surfaces are usually sixty-odd years old.
| Check the manifold face | a warped or previously milled intake will not line up on the gasket. Test fit dry with the gaskets in place before any sealer comes out. |
| The valley rails are a sealer joint | on a Pontiac, the front and rear valley rails are sealed with silicone rather than a gasket on most builds. Have the right sealer on the bench. |
| Do not force a later gasket | port outlines and water passages moved. Trimming a 1965-and-up gasket to fit an early head is not a fix. |
If you are not certain which of the two early patterns you have, count the years on the head castings and measure the port opening before ordering. These sets are inexpensive, but the wrong one costs you a manifold removal.
