BlueZ31 Posted November 28, 2008 Share Posted November 28, 2008 anyone know the maximum amount that can be shaved off a vg30e head before valve clearance/intake manifold mounting issues present themselves? ive got a new block assy in place and im looking for a way to add a little oomph to my DD, ive got a good mod list going but i figured a CR increase might help... and i know cams affect the dynamic/static CR so heres the specs INTAKE TIMING Duration:256 Open: 9 before TDC Close: 67 After BDC Cam lift: .281 Valve lift: .425 Valve Lash: .000 Exhaust Duration:256 Open: 67 Before BC Close: 9 After TDC Cam Lift: .281 Valve Lift: .425 Valve Lash: .000 Overlap: 18 Deg. Taken at .050 Lifter Rise Intake Duration: 202 Deg Exhaust Duration: 202 Open: -18 before TDC Open: 40 Before BDC Close: 40 After BDC Close: -18 AFter TDC i was told .030 was the limit for vg30e's, anyone else tried head milling or thinner gaskets? id appreciate any advice greatly, ive only got 1 1/2 weeks left to get it assembled and enjoy it till i ship to parris island..woooot!
