stock to aluminum heads

this can happen. if it were my money I would do a cam swap . you are doing alot of improvements on the car as it is. your mph is good for mid to low 11's now.
wouldn't be the 1st time a cam change was good for a couple tenths.

I checked my cam spec's now: 546-566 without the .026-.028 lash with the 1.5 :1 273 rockers
if I go to 1.6 :1 rockers spec's say 582-603
I leaning towards that with 2.02's
