Application

  1. Can be used with most oil filter systems and transmission/starter combinations.
  2. Does not fit '55-'57 Chevy cars, Camaros, or other modern vehicles which have a crossmember below the engine's center two exhaust ports.

NOTE: Stainless header tubing when exposed to exhaust temperature will cause the finish to change color which will vary with the exhaust temperature. Please note that the finish of the header when the engine is started, will change to a light champagne color to a darker gold finish and in some instance may even turn dark blue or purple. This can be polished back out when utilizingBlue-awayorSimi-chrome polish, but please note that when the headers reach running temperature again, they will immediately change color.

Overall Assessment

Customers value the product for its excellent fit, indicating it aligns perfectly with a 61 belair / 355 sbc / airbagged. The product features a robust and well-constructed flange, ensuring no exhaust leaks. Its clearance is highly appreciated, especially for bagged cars that lay flat. The headers may change color after usage, a characteristic some users found reminiscent of old-school motorcycle exhausts and not a negative factor. If a shiny appearance is desired, some upkeep is required. Overall, the product's quality, functionality, and nostalgia-inducing attribute have led to customer satisfaction and repeat purchases.

Using these headers on a 61 belair / 355 sbc / airbagged. Headers fit perfectly, nice thick flange - no exhaust leaks. Work great because car is bagged and lays flat - great clearance. They do change colors after usage, but it reminds me of the old school motorcycle exhaust days when they changed. Doesn't bother me - but if you want to keep them shiny you will be cleaning after every drive.
