Reason I ask is....why don't you load the thing up, bring it down here and let me look at everything with you. I'll even show you how to lap the valves in and let you do it yourself. That is, assuming the guides and seats are good. You don't have anybody who you can trust to look at all that do you? I'll tell you straight up if you can run something without machine work or not. You don't want tp put heads together with bad guides or seats. We can assemble it right next to Frankenteen.
