domed piston for scj or p-51 heads

Does anyone make a domed piston that will work with scj or p-51 heads?

Which one...?
Although both heads can use the same flat-top piston they have different shaped combustion chambers which require a different dome for either.
Diamond has one for the SCJ; I don't know about the P-51.

The dome needs are so little that, in most cases, I'd doubt that the SCJ would have to have a different dome than the P51.

I can only guess that you are not used to building high compression 480 and smaller size engines ... the dome shapes are drastically different.
On a 550 inch engine and above where a lot of dome volume isn't needed then a P-51 dome may fit both but, an SCJ dome will never fit a P-51.

Thats why I said scj OR p-51.

I had Diamond do a domed piston for KY's P51 562" engine......so yes it can be done. It was custom.
