If its hyd cam lifter preload may have been set too deep or the valvetrain components have not been correct at initial build to arrive at the train wreck we are looking at now.

You are right Jac Mac, my bad. I was thinking of my Modmotor block and transferring its dowel placement to the Windsor family. For those with curious minds here is a pic of the Windsor block deck clearly showing the dowels on the exhaust side of the deck not the other way around.
Apologies for the misdirection guys.
