How many is too many?
I'd set them at .018 and .026 and see if the bottom end comes back some. It should. That cam is a bit much for your converter. The old heads obviously had better port velocity to help compensate for other inequities.

Sorry I dont read your post anymore. Go away If you dont have anything to say.You seem to have all the answers as to what it's NOT, yet you don't know what it IS. I find that humorous, actually.

Yup, much improved heads and no gains ,again, indicates the bottleneck is elsewhere. Even Comp Cams recommends 3.91-4.10 gears and a 2100-3100 stall for use with that cam.I have set what comp cams advice is. Cant remember it.
These RHS have smaller intake cc than my old heads. These RHS heads looks almost too small from pushrod pinch area. They also have 10 times more better looking exhaust ports. and multi angle valvejob that I didnt have in old heads.
Maybe few hIf you don't have an X or H pipe adding one will also help your problem.
20 is my idle timing. Im not going backwards in cam maybe I do these upgrades what you succest me to do. 2 mph better equals something like 20 hp. I was hoping more I dynoed my old engine and it was 300 hp with smaller cam, old heads and 8.4 compression ratio.Yes your converter and rear gears will affect you're trap speed. If it can't get moving off the line it will not show it's potential. BTW the carb and exhaust are to small for that combo and your gears and converter are wrong too. If you're dead set on the gears and converter put a smaller cam in, you'll be much happier. The heads picked up almost 2 mph so it is making more power than before.
BTW where is your initial timing? With that cam it should be 18-22°.
What is you vacuum reading at WOT bet it's high. Indicating you need a larger carb, Torque converters are all about torque multiplication and if it stalls early you get NONE. 2200 is pretty much a stock converter. Exhaust back pressure can absolutely kill output.
If the cam is in at 110° that could hurt it some too IMO, 106° would wake it up on the bottom. Also it needs to breathe with better heads and more cam the problem is compounded.
It is in "stock" location what comp cams says it should be (if you meant intake centerline) I bellieve it can detonate if advanced too much.If the cam is in at 110° that could hurt it some too IMO, 106° would wake it up on the bottom.

vacuum was 20 something. What you mean leaked? I have not looked compression test yet.
