Review on Flowtech 11152FLT Standard Headers by Christopher Gulledge

Do not buy these for the Cutlass Supreme 86 5.0L

I bought these for our 1986 Cutlass Supreme 5.0L/307. Landing on the engine is great until you want to put the starter! So I decided on a mini starter. still doesn't fit. After a few hours with BFH (pipe half flat) cleaned the starter. They baked the finish (don't know why they can't factory paint them with header paint) and painted them with header paint. Thermal cycles passed on the engine stand. I was about to install the engine in the car and hit the frame from both sides. The driver hit the top of the cross member and the passenger hit the back of the cross member. 3 round trips, a few BFH hits and a fit. NEVER recommend this title to anyone!

Pros
  • Port Sealed O-Rings
Cons
