Valve spring wise the E heads will have no problem with the lift of the 703 Cam with 1.5 factory ratio rockers, but you will need to play with factory Q-jet a bit in terms of that Cams idle vacuum.

"Valve spring wise the E heads will have no problem with the lift of the 703 Cam with 1.5 factory ratio rockers..."
How about the catalog stated 120 lbs spring pressure ? If that is in fact where they are at. And the 0.181" away from coil bind ? Your opinion on those. . .

I'd probably be asking Paul what kind of pressure he likes to see on those voodoo cams, he's setup more of those and has more dyno time on them than anyone I know.

Personally I would not trust what a cam salesman would dictate, nor any general spring pressures listed on the Lunati website. .

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
