GT750 Cylinder head nuts
Posted: Tue Apr 08, 2014 9:55 pm
Before I send off my cylinder to be decked 3mm for the spacer and mill the head .030" I thought I should check if my cylinder head nuts are going to bottom out before I can get to full torque. So after adding the head gasket thickness, the thickness of the milled head and the thickness of the cut cylinders, the cylinder head nuts bottom out very close to my total installed height of all the parts. I ran a tap through 1 head nut and got very little additional thread. The nuts are tapped about 1" and the cylinder studs have about 1" of thread so the nuts are fully bottomed on the studs.
Without drilling and tapping for more thread the nuts still bottom out where the un-threaded portion of the stud starts.
I was thinking about buying some stainless flat washers to put under each head nut between the sealing washer and the lock washer. I'm pretty confident that will give me the room (threads) I need to torque the head properly and have ZERO problems. Besides those lock washers tear the hell out of those sealing washers when torqued. The extra flat washer between the lock washer and seal washer would definitely deter that situation.
Have any of you motor heads ran into this before and have any cost prohibitive solutions to offer???
Thanks in advance
