This would be my pick. The new XE profiles are aggressive and give a wider
power band than before with better vacuum and response. Besides, I have
been reading your posts for a long time now. You are one of us, in that you
are always interested inn learning and trying stuff. You will build on
this, and this cam will respond well to future mods.

This cam profile is ancient. Don't bother.

Too big for stock stuff.
The D3 heads are great. The exhausts are not a big deal, and can be made to
flow almost as much as the C8-D0 heads by someone who knows how. Scott
Johnston is the master of the factory 460 head these days, and he did my
C9s. Yes, you can get 220 cfm from those exhaust ports.

That's his website. He posts everyday on the 460 forum:

Anyway, those heads are good.
