* Intake Lift- .414"
* Exhaust Lift-.428"
* Intake Duration @.050"- 191
* Exhaust Duration @ .050-196
* Lobe Centerline-111

According to a few sources, the vortec heads (062 cast) can flow up to .460 lift stock. I haven't been able to verify if the heads on this short block are the 062 cast.

L31 short block heads - 64cc,1.94" intake,1.50" exhaust

Not flow .460, they can handle .460 lift. But that's just the guide clearance. The valvesprings are too weak for more than stock.

I run 062 Vortecs
