Pat indicated on Facebook he intends to sell them for around $799.95 for a pair. Thats quite a bargain

I may have to build a bigger motor

I think this is going to be a fantastic all-around hipo street head.
Too many people have the "bigger is better" philosophy. I've done the big valves in welded stock casting, Comp Eliminator-type and stock ported heads in a number of different engines, all used primarily on the street as I'm not a racer.

I guess with age and experience comes just a little bit of wisdom, as my last motor which has Panchito 40x35.5 valves, is the best, all-around street motor I've ever had, Period.

A 40 mm intake valve, in the right type of head (maybe not an ACVW) can support 200+ HP. I didn't used to be a believer in high-port velocity, just "more flow must be better" but with higher port velocity, you get better combustion mixture, lower risk of detonation (better swirl), more responsive bottom end and consequently more torque and better overall flexibility of the motor.

For most of us, who I take it are looking for the best street combination, these heads should be a substantial advantage over current offerings and certainly "large enough" to provide more than enough performance.

You don't need 44-46 mm intake valves, 48, 51 or 58 mm IDAs and huge exhaust systems for most street applications. Smaller can be better, try it!
