Supreme Speed Salon (87 T Top Salon build)

I was advised with correct information. The 3901 Hooker headers were for a different body style. At the time of this picture I had no idea, only that they would fit Old's engine. I discovered I have a set of headers the are no longer in production. But they were specific to 442 or Cutlass Supreme for the gbody style. Learning daily and thankful for all that participate to encourage and properly inform each other on a daily.

You are more patient than I am, non running or driving cars drive me nuts. What headers are you using?

Hooker 3901 it says they are Olds competition headers.

Those won't fit your G body, if the number is right.

I hope you're wrong but I do have two other sets. I suppose I will do a test fit before applying wrap to ones I won't use.

I wouldn't waste time on the wrap unless there's a hairdryer involved.

No hairdryer, I thought it would help rid of extra heat from the engine bay.

If the short block is right, you're golden. TRW pistons scare me; didn't go back to see what you got.

I'm not sure of the pistons the engine was professionally built

Dawg, now is the time to fix it if it ain't right. Can you turn it over with the plugs out pretty easy?

Only Hedman and Flowtech make affordable full length headers that fit your car, they must say 260 through 403, 78-87 model years. The Flowtech rust quickly, have thin flanges and have questionable fit.
Those 3901 are for 68 through 74 A body, 260 through 403. Hooker used to make G body headers, no longer. The TRW Speedpro forged pistons used in your motor need .004" clearance minimum. The instructions say .002", if installed that tight overheating happens no matter what cooling system is used. Hopefully they weren't installed too tight.
