Default Cathedral port head and l92 piston?

Can u put a cathedral port head on top of this piston? Here's a link to the piston, and from what I have been told, the exhaust valve is what has been moved or clearanced or something.

I would think it depends on the valve sizes in the cathedral port head and PTV, but most likely it would be ok.

It should work with no issues. Only thing I would worry about is the PVT clearance.

I cant see any reason why having that piston would have any thing to with a cathedral port head not working. In the end its about PTV clearance, compression, etc.

I would think radial PTV could be a problem is some cases.

I'm running 243's with ls3 flat top pistons. Comp 54-444-11 cam and I run 1.8 rockers. Trying to figure out now what the biggest cam I can run is. I have some valve drop measurements if that would help you any.
