how far down mill 243's
i have a couple of ported 243's laying around..
i wanted to know how far down can i mill to get to 58-59 CC, w/out having PVC problems , or having problems with the intake.
my cam has a .581 lift on a 112lsa, that's the highest lift im going with.

I am wondering this to. Except everyone I have talked to has said that if you mill them you have to keep you duration 230 or below for got ptv. Hope someone can shine a little light on this. Thanks

my exact thoughts too...bullshit...
someone needs to learn how to measure...plenty of clearance too, not even tight...
measure yourself guys with a SOLID roller...
some measurements I have taken
stock 241 heads unmilled, stock mls gasket 230/230 111+2
intake .086 exhaust ~.120
TFS 215 57.5cc chambers, .040 gasket, 239/243 110+3
intake -.020 exhaust .040
