What cams are you guys running with .030 milled AFR 205s and uncut pistons?

Using Engine Analyzer, If I assume pistons @ .007 out of the hole, . 030 milled 205cc heads, and valve drop of .120, and a gasket of .041, I get the following clearances:
220-224 114+1:
Intake: .090
Exhaust: .091
224-228 114+1
Intake Clearance. .083
Exhaust Clearance: .083
I haven't been able to verify valve drop. One vendor did indicate that the drop with a .030 milled AFR 205 would put drop @ .120. I also seem to remember Tony M saying valve drop with a stock 205 was .183. Can anyone help here?

Anyhow, I had the Dart's milled to 59cc, .040" gasket and runnin the X3.. I notched my pistons .085" (per LGM) to get the "safety" net.
It took longer to get the heads tourqed down then to notch the damn pistons.. So, I agree with N4cer, notch the *******!
After 3 pulls on the dyno after the whole top end assemble and the tranny on its last breath, I got 421. There is ALOT more tuning to do as the car is big rich right now.

I belive Tony uses a smaller cam and on a 114 lsa, on his setups, which are basically as close as you can get for pvc, when using the cometic gasket.
