Part # 91003058 Notes Will not clear roller rockers Reviews Good Stuff but know that the baffles won't work on a Pontiac: Rated by SIck472 May 12, 2020 Summary: I put these Pontiac 400 with 6X heads and stock. Baffles are included. Cons: Arrived needing to be cleaned. All in all, I like them.

Sold as a pair. Don't even screw them in, throw away and hope you don't need baffles to keep the oil from getting breather. They arrived with about 20 minutes worth of polishing grit/dust needing to be cleaned off toothbrush and parts cleaner. Pros: Unique looking.

The baffles will never work. For small and big block V8 326-455, 1955-79. For half the price. If this was going to be a show car, I would return them for the price paid about $200.

Outbreak, and Morose. Yes, I recommend this product. Some scratches on a few of the polished fins, but not too bad. The person polishing the covers over did it and polished a few spots that should not have been.

They hit the rockers and cannot even be modified enough to work. Specs Sold in Quantity Pair Valve Cover Mounting Perimeter Bolt Material Type Cast Aluminum Color Natural Hardware Included No Baffled Yes Gaskets Breathers Top Finned Grommets MFG.
