its hard to see but its almost as if the valve seat is a bit smaller than the actual bowl area. these are the 78cc 310 cnc heads. its a really small area about quarter inch long and its right where the seat wall meet. u can see where the maching stops and cast starts, its right in that area.



i was gonna get so.e 80 grit sanding rolls an just kinda clean up.the rest of the as cast area and try slightly blending that area in...but then i seen the epoxy i mentioned.


what do you think

I'm gona get a set of those CNC bare heads and see if I can improve
on them. I'm really curious what they look like and how they did there
porting on the heads and just how far they went with the porting?

Those are the ones that are not showing up on the SM page. I checked I don’t see them either.

I feel a little sarcasm 🤣 but jokes aside , thats what should really happen., everyone get their panties in bunch when china makes copies that eventually kill domestic manufactuters and put people out of work. But people just keep buying offshore crap.

Id rather be slow and using my hot rodded stock parts than fast on chinese stolen designs. 🙃
