	I never revved the engine very hard until the pressure came down.
And I
	used an HP1 on and off over the years when I could find one.

If you or anyone else wants a HP1 filter (Fram) I found several
at pepboys....forget the price maybe around $7 or so...

Can't find them ?  I'll buy them for you and ship.....

	The pistons I have are Wisecos and only have one relief cut in them
for the
	intake. When I asked Kip about valve to piston clearance, he
replied,
	"Don't worry about it. You've got tons of room." But I'm going to
check
	anyway, just for grins....

	But how can you run 92-93 octane gas on the street with 11.1? Or is
the
	answer, you don't?

	You're welcome.
