However I am a bit disappointed in the performance especially low down. Would you recommend the TFS track heat manifold and if not whats a good intake match.
Cam is Comp Hyd Roller .578 lift plus Holley Vac sec
Had this setup with my Aussie 2v quench heads and performance was impressive

The current camshaft is 290°/290°, 110° LSA, 70° overlap. That's a big cam to choose for somebody looking for performance "down low". Since you liked the performance of the engine with the Aussie 302C heads, the swap to Trick Flow heads and the choice of the big cam lead me to believe you're looking for higher output from your Pantera's engine, would that be accurate?
When you changed the heads, did you change any other parts simultaneously, or just the heads? By the way, which Holley carburetor did you purchase and install? Does the short block have dished pistons or flat tops?
Rather than comment on the quality of the Howard cam, if you don't mind I'd like to understand what performance and power band characteristics you are attempting to achieve. Could you also share with us what troubleshooting you have performed to the current set-up, if at all, in trying to understand why it doesn't perform to your satisfaction?
