HSR Heads

I do not own a HSR but I am doing research and what am I missing here.

I know it does not have any EGR provisions but at the same time I see where people are using it on stock L98 heads??

Can this intake bolt onto stock L98 engines with out changing the heads or not?

Mine is drilled for both style heads, I just needed bolt spacers so that the bolts seat against the intake at the right angle for 87 up heads.
