Here are some pics of my 15° W2 heads for a 48° lifter bore block. I'm using an early R1 48° block. Going to be a nice little 360, all iron I guess to be different  Flow #'s to follow. I think the 15° valve angle would work better if the port was raised more. But they work good enough for what I want out of the engine. Chamber will be 48cc when finished. Brian

And....flow #'s.
2.08 intake x 1.60 exhaust
28" 4.030 bore
Lift Int. Ex.
200 145 108
300 218 158
400 261 206
500 295 229
600 316 240
700 327 240
Just some pics for fun. I'll post more pics of the build as things get done. Block is done except for drilling the lifter bores.
Crank is balanced, etc....
Think I have my engine sold, so hopefully I'll have this in by the end of summer!

Actually I wasn't joking, a buddy of mine bought a set of heads just like yours and is looking for some help in doing a home port job, he's asked me for help (templates) if they exist? At any rate, the 4.25 bore/flow deal went right over my head as well, please enlighten me?
I figured you were joking, cause template porting won't get you anywhere close to this kind of flow.
Anyhow, if they are the 15° head, I would leave the 2.02 valve for now, and do some chamber work around the valves and a good 4 angle valve job.
Use a nice fat 30° back cut on the intake valve and call it good.
Look at the pics closely, you'll see there is a ton of work in the intake ports that I did.
Plus, alot of sb's will not want this size of port.
You can also slim down the guide boss some...

Just looking to give my buddy something of a guideline so he doesn't make an expensive mistake. Thanks for the suggestions.
