Headman's vs. 3 tube headers
I have been running Headman 3/4 tube headers on my 78 T/A. I have the engine out at the moment and I will begin putting it back in this week. Awhile back I picked up thse ceramic coated used 3 tube headers. Would I gain or loose and power/performance switching to these? Im running the engine combo in my signature. It is RPM limited due to the TRW pistons, stock rods (ARP bolts) and unfortunately it being a 557 block.
