does he do different degree`s of porting? if not you don't need any way to distinguish them apart,is so like us (& most other porters) have different levels of porting & need some way to categorize them

I have used JPrecision . I got their 2B heads . I'm preaty impressed with the gains .
Could you Pm me if you could on your concerns .
I figured they make AV&A Valves and guides, I figure they would have a preaty good handle on it.

F.K.

He is long retired. These were done in about 2004 or 2005, early on in the twin cam horsepower wars. He set them up for my build using SE flattops and Andrews N55G cams, so I am assuming a "stage 3" type of work, but I have no real idea. I think it has Kibblewhite valves, but it's been a while since I looked at the receipt. I know they were not cheap to have done. Since then there have been many more cams and info made available.
I can tell you that they have lasted for over 85,000 pretty hard miles, and I was just beating hell out of them again last week. Poor motor. Not sure how it is still holding together.
I know they will need rebuilding one day, but not sure if they can be done, or should be, or just start over with new cores and cams.

At the most, replacing guides and seats is all you should ever need to do. They should last as long as you do.

That's what I'm hoping for.
