Yup...they will hit slightly on the intake valve reliefs. You can send them in to us for correction. I was just about ready to respond to your email to us.

the 8.5:1 JE piston top design is better than that of the 8.0's IMO
dont cheap out on something as important as pistons...

The 8.0s will clear fine but are not as effective in horsepower production. The 8.0s are also much heavier than all others as well.

Quoted for facts, thanks
So the stupid ski jump design is strictly for emissions. They sit low in the cyl and lack any sort of quench also
