TFS 58cc heads, flow 300cfm at .550 lift, and have 2.05" intake valves. They were originally ported by Ed Curtis at FTI and then later ported more by Rich Groh of RGR Engines. They are currently not back fully assembled because I was going to change the springs - I'm not sure the spring weights, but they are some pretty heavy springs. Full Race valve job with stainless valves and titanium retainers, COMP springs, viton seals, radial locks. Spare TFS seals included.
These heads were originally ported for and used by Bill Perkins aka "Perky" who had them on a championship winning NA car that went a best of 9.39 @ 144mph with an NA 145ci 14:1 motor in a 3200lb street car that made in excess of 650hp – so they are pretty badass!
I bought these heads from Rick at RNH performance, and then Rich Groh had them at his shop for me until last week - both can confirm the legitimacy of these heads and can tell you they are some wicked heads. On a boosted motor with only10psi, these heads would make a 10 sec car with ease!
They have a beautiful black powder coating job on them, no flaws. Only ill thing to speak of is that there is some light rust on the valve seats, but it comes off with some steel wool scrubbing.
$2000 plus shipping.
