At 98000 miles, I'd fork out for a new set of lifters.

It's hard to beat AFR heads and some of the camshafts they suggest. I'd call AFR, as for Tony Mamo and ask him what cam he suggests for the head you pick.

Problem is, some of those AFR head/cam combos also need headers to really work well.

If I was going to go aftermarket on heads, AFR would be my first choice.

If the car's a cruiser and not a drag racer and the cam is stock or you're going to put in a "good street cam" and the car as a 3.42 axle, loose the racing torque converter.

The car may actually be quicker 0-60 and will get better mileage.

Also, if you have 373 at the wheels, now...that's pretty darn good for bolt-ons. Was that SAE-corrected or Std. corrected?

Radiator yes, condenser no. You can gently move it far enough forward to clear the cam.

I worked with Tony on my setup and have his ported FAST, chamber worked AFR 205's, and the AFR 6016 cam. Very very responsive at any RPM. I agree, contact Tony.

The difference between your shop and Tony is Tony designed the AFR heads.
