SHO Head bolts
Can they be reused?
The manual says no reuse, but it has been wrong in the past.
They are about $10 a pop.

I'm surprised it says you can't reuse them. Every watercraft that I've worked on the bolts were reusable. I've only worked on 2 strokes though

That's what I was thinking, stretch... I ordered some anyway. Just a holdup now...

Why get new head bolts when you can slap a Cylinder Head Stud Kit on there? Especially with the resources you have and the power you obviously like to make, you'll get better fatigue strength, better alignment, and more accurate tightening and clamping force for improved head gasket life, and less 'block-distortion' after the head is torqued down..
That's why motors r bored and decked with this special deck plate in place (this is Riva's custom-made plate for the SHO). The plate simulates the 'pulling' forces of the tightened head sitting on top......then when the block is bored and honed, these other forces that can distort bores of the block are taken into account and compensated for....

That's the next stage about this time in 2011
That's when the insides get replaced.
BTW, were you ever able to get any $ numbers for doing the engine work?

Remember the old dotsun cars/trucks , they had one time use only head bolts..out of curiosity when you get your new bolts measure them with micrometer and see if they are the same length as old ones.
