16 Positive Seals for intake and exhaust, BLUE VITON

BIG BLOCK CHEVY, 3/8" X .615"/.625", set of sixteen- eight each

Includes a total quantity of 16 seals.

This set fits stock guide diameters of .615" on the exhaust and .625" on the intake.

It's important the user verifies their BBC has these guide sizes because not all BBC heads have the same size guides. Some use .625" on both and we have seen guides which were .602" on the intake.

It's best to measure the guide diameters in advance. If you can't find what you're looking for, contact us. (don't leave a message, just call back or simply use the "contact us" link)
