Oh boy do I have alot of studying to do before I can follow all of the excellent advice I'm given. Dave, all I want to duplicate, actually, is the performance from an acceleration and reliability standpoint. Does a 1.8 head with 2.0 valves and seats need additional modification to produce a reliable, relatively efficient, engine that has the performance of a 2.0 with a stock 2.0 crank, rods and p&cs (besides boring out for the larger p&cs)?
