Going from Ferrea 2.20 valve to 2.25, Is there a better flowing valve for ported STREETS?

Saw ferrea had a Chevy valve which is 5.271 with a 12 degree compared to a 10 Degree in the Ford. Thought the Motorsport was the best flowing but don't think they make it in my length and 2.25 size anymore.

Flatter is better on all but a hemi , IMHO anyway.

I tend to agree, my friend was doing some Brodix-2 BBC and it loved the flatter backside. I probably will have to try different valves and cut the back to what it likes.

Ford hasn't offered that valve in about ten years but one that is .100" longer can be gotten from Jon Kaase.

He uses those in his P-51's.

Thanks, thought the P51 would have a good valve, but don't want to buy both exhaust and Intakes and pushrods My buddy have other brands to test with. Maybe we can learn something playing with the backcuts. I found some 6000 series Ferrea 2.25 valves atleast the right length.

I have found the Ferrea 6000 series valves a close second to the A429 intake valves.

6258 if memory serves. I'd have to double check.
