G60 Valve Cover

[area53 at validpath.com (Jeff Toomasson)]

Thanks for the info, Neal!

Seeing as this will be my first foray into forced induction, I'm leaning toward 
starting w/ the stock 3A pistons and stacking gaskets (w/ a x-flo head). Not 
necessarily from a cost standpoint, but in case I mess something up. Actually, 
I'm still completely on the fence about the pistons!  :) But it sounds like the 
stock filter is the way to go. Any idea how much they are new? I made have 
tossed mine during our recent move...

Thx again,

JT
