I have always thought it was for a tight fit in a frame,but have heard it gives better performance....Is there any truth to this????I want your oppinions....

They are one sharp looking head thats for sure....Dunno John-John. Never got around to trying one but they sure is sharp looking.
My base gasket blew out on one of my motors,so I pulled it and used hi temp silicone for the bottom gasket and the piston hit the head so I put 2 head gaskets on it and it fixed the problem....If I buy a slant head(being it is a dome shaped piston)I will put 2 head gaskets on it....Yup.
The PK80 i have will need both head gaskets for clearence.
Without them the piston hits the head.
Have to mill the head to get the proper squish.
Yes. I was trying to explain to someone last week that the Zoom slant was near or beyond the limit of practical compression and the billet had no advantage in that dept..47.1291cc / 5cc = 9.43 : 1 "SOUNDS LIKE TIRE SKIDDING TO ME"
I wouldn't reccommend going much higher without some serious octane.
This is also about the same as the Rock Solid Billet head.
