Kaase Boss 9 heads

Are the valve locations the same for Jon Kaase Boss 9 cylinder heads and C&C motorsports Boss head? Why this question? looking at purchasing pistons and Jon Kaase sells Diamond pistons for the Boss 9 head. If I was to order them from Kaase would the valve reliefs be in same location for the C&C Motorsports Boss heads heads?

Got to watch the combustion chambers they are way different.

Also valve sizes for radial clearance.

Give him a call and get first hand info from him before ordering.
