Evolution LS/B20 VTEC Dowel Pins

Tired of having to bring your cylinder head to the machine shop across town to have the dowel holes drilled? Tired of spending $75-100 at the machine shop and waiting a week? No more. Pro-Fab Designs brings you the VTEC conversion dowels that make cylinder head swaps a snap. Simply insert the dowels and install the new VTEC head on your LS/B20 Block. (Please note the oil supply hole in head must still be tapped and plugged - we offer the kit with plugs for that below.)
