I'd like to see the flow data. I'm sure those heads flow very well with some work. I certainly don't think AFR heads are bad, but I do think they are often hyped up, as if they are the only heads that can make power.

There's a lot to be gained power wise in the intake manifolds also. I did all the cam& head work but felt there was more in it. I sent my intake with the Head & cam# to Wilson manifolds it made every work together

I'd pull the heads and have Billy's dad do his thing.
If there is evidence of valvetrain instability or excessive wear that you think is from the cam, THEN look into changing the cam.
Changing the cam just because others have reported issues, without evidence of problems of your own after 60 plus hours there is no real reason to change the cams. Even if you could gain 40HP, you won't net any significant gain once in the water.

It's all if I have the funds at the time, I have other places to spend money also, 1000 to change cams is one thing, 6000 to redo heads up is different...

You can get new billet HYD rollers, for less than 1000 dollars. I wanna say the last price I got for a lunati billet with iron gear, was under 400 each.

Even better... A 30 hp gain on each side would at least get me a tad over my old engines and then I'm happier and redo the rest later or just put pro chargers on

Bill called me, might be pulling heads and intakes going to dad Klein ... Deciding if gains to be had will be worth money spent, I question carb and intake not being dominator a he's convinced I don't need doms to see gains... Said my carb flows plenty but for proper can I need exact flow numbers not advertised.
