Head nuts

[Corventure Dave]

I make a point to pre-torque test each head stud before assembling the crankcase. I do this with a piece of tubing and 2 flat washers. I would rather have a stud pull on a bare crankcase, than down the road when the heads are going on.

As far as the original post about head nuts. Living in the South West, there is little stud or nut corrosion. I have been building street engines
for decades. Re-using good original head nuts has never been an issue. Then again... I have a box full of excellent original head nuts to select
from.

Dave,

Pre-torquing sounds like a REALLY good idea. Next time......

During my last rebuild I skipped testing the head studs because none turned loose during disassembly and the block was from the West coast and there was NO corrosion. Well ------ A top stud on the end pulled out at a mere 15 ft. lbs. on assembly with ALL the aluminum threads on the stud - AHHHHH! So off came the head, cylinder, piston to install a Time Sert (Ray Sedman at American Pi has the one with the correct depth). Murphy's Law!!!

Wicked sexy looking exhaust you have there..you will have to put a file on here so we can hear it.

Took it for a drive this evening...... sounds like an E-Type Jag with a sweet snarl at top end. More than I expected!
