2.10 intake valve better than 2.165 for 4.030-4.060 Bore!
235 CC better than 255 CC for 408" street/strip!
Tony will also have a Nitrous/Forced Induction Exhaust Port
Option for his MMS 235 Heads, not sure at what HP/Boost
Threshold that would be most applicable/beneficial
(200HP Shot/10 PSI)? SWAG

I like the Cam Specs, I would have Kip @ CAMMOTION grind
It for you, better quality steel, gentler lobe profiles for better
Valvetrain stability/ durability, and Phenominal customer service!
