Hello Q-List: I know this question has been posted before, but can a 20V non turbo head be fitted to a 10V non turbo block? If yes, what needs to be changed? Background: building a stroker motor, but the piston diameter of the 20V is 82.5mm vs.81mm for a 10V and pistons are only available for 81mm and the longer crankshaft from a 2.5L Eurovan motor.
