Ford vs CHI vs AFD vs TFS heads for Stroker
#11
I am a big fan of the AFD heads. Mine are SP4V. With the 408 stroker kit and my recent cam swap my engine builder estimated 550-600HP. It is a blast and has been very reliable since I got away from the Comp lifters. DO NOT BUY COMP LIFTERS!!! I had several failures in a very short time. Even the replacement ones they sent would not pump up right out of the box. I am also running a torquer intake on mine with the ports epoxied to match the heads.

1971 Mach 1
408C Stroker
C4 w/3,000 stall
8.8" Rear w/3.73's
Disc brakes all way around.

Flat tapper or roller?

Mine are hydraulic roller, but have heard of failures on all their hydraulic lifters. My engine builder will not install them in any motor any more. And he WAS a Comp dealer.

That’s crazy.
I bought a set of Lunati link bar rollers, but I always wonder....

Thanks for the heads up.

Those are what I ended up going with. Been in the motor a couple years now with no issues.

The $400 street ones or the $700 race one?
