Valve ideas for ported 915 J's

San Diego East County. Like waaayyy way east, lol.
Ive got a good friend ( a Dodge vanner) that is going to port them. This will be his 4th or 5th set of J’s. I was thinking about reaching out to you but he’s a good friend and doing the work for a more than fair price. He had his last set in our preferred machine shop, Cogswell in Chula Vista (Mopar racer) and he said they looked pretty good. I’m happy to see my friend getting better. He’s an Army vet, went to School of Automotive Machining and Technology on the GI Bill. Trying to find his foothold.
Good for your friend, and vanner. .nice.
Do you flow these afterward? or do they just "look good"?
Never heard of cogswell.
I've heard of ed hale, but he's long gone.
