Honestly. your best bet.. call a cam manufacture and get a custom grind made for YOUR motor...
Good luck!:smile:
It's also good to know what your actual flow numbers of the heads are. There is a ratio between intake and exhaust flow cfms. Once the flow numbers are known then you can choose your cam profile.

I have a 109 stroker and I use a single pattern cam with aluminum heads. If the exhaust side is up over 70% of the intake than from what I have read from different (old) sources a single will usually make more power. I went 10.1 at 21/22 psi of boost with a slipping trans at that time, just think what 31 psi would do. Per Gale Banks all things being equal every pound of boost increases hp by 7%.
What cam are you using?
It's a street car, so I use a 224 hyd. roller with 110 degree lobe separation.
PS: I have used this cam since 1999 with a .030 over 109 and was going 10.5 @130 mph back than at 24 psi of boost and all on the foot brake from day one.
What lift is this cam & what rpm do you shift it?
