Default TFS heads or AHP rebuild

I know there is a cost difference but I could sell my factory heads an recoup some. Is there a guide wear advantage to the TFS? I do want to install a mild cam with either head set I go with. Is there a power increase with the TFS over the factory? What would be roller rocker arm options? Help me out guys with some opinions.

If you’re thinking TFS heads you need to talk to Tony Mamo. It will be pricey but worth it.

khole has a new head porter and hasn’t had any reported dropped valves with his work. I’ll always vouch for him or wcch

I’m not sure how accurate your info is but last post he had 2 porters that were very seasoned. He posted this info about 1 month ago.

We have 2 full time head porters (one comes to us from Cosworth Racing's Formula One Cylinder Head Department and the other from TRD's Indy car program).
One has been here for years and years. The other has been here since early October of last year.

Just thought I would jump in and clarify that in case anyone was wondering.

That would be a great setup IMO.

AHP, as I'm not a fan of TFS' stainless intake valves.

AHP here for me also. I just did my swap last week and my valvetrain is a lot more quiet than stock
