Doug Thorley Headers with SB Trick Flow Heads

Dennis Hilliard said

I am sorry to here that. I still think that the TFS head is not matching the stock head where the exhaust bolts up. I can't believe a header can be this fare off, I ended up using motor mounts from a conv whice raised the motor almost 1/2" and they still hit everything! I feel the pain .Cheap headers next time, I called TFS and never got a clear anwser, so until someone can bench one with a stock one we will never know for sure.

I'm not sure what happened in your case, but I've been following it.

I can tell you I've never owned a set of headers that you can raise the engine a half inch in the chassis and have the headers fit. There just isn't room.

Since 1980 I've used 5204 or 5303 Hooker headers on any A body I build. They always fit, make more power and don't drag the ground.

But, IIRC the 5204 is now about 800 bucks and the 5302's were 850ish in 1984.

Too bad they don't make the 5303 any more. Any decent 340 should run them, and any stroker it's about mandatory.


Edit: I just looked and Jegs has the painted 5204's for under 700 bucks. Not a bad price for that header. But you can't have power steering with them.
