There was a link from SOHC4.net telling you how to re-set the photobucket pictures, it worked for me with Firefox 57.??.
Very few people are going to pay the Photobucket 'ransom' of $400.00 a year, I sure as hell ain't doing it particularly as it's possible to post pictures directly to site now (just have to find all the hard drives and flash drives where pictures are stored  ::) )
 The way to find out what you need is have block bored for pistons then do a dry assembly without rings to check dimensions. Use a copper base gasket for better heat transfer to crankcase. When I first 'invented' the GS piston conversion I wasn't aware there were production variations in crankcase deck height (plus got lucky) so didn't tell people to dry run first (plus, I've been doing this so long I assumed anyone building a modified engine would automatically check)
 I ended up taking about 0.025" off head surface plus 0.020" off block to get 'zero deck' It would have been easier to just get a thinner base gasket from Lani

I have a habit if researching the crap out of stuff before I actually commit to it, this bike has been and adventure in NOT doing that. LOL there were mistakes made (anyone ever see a scrambler exhaust on right side of the bike? no? that's because it interferes with the kickstarter.... go figure)

I seen it once, just a bit of MAP gas and a simple tweak..Viola, easy peasy.   ;)





The real trick on CB360 is keeping clear to access the dipstick.

Call Lani at http://www.coppergaskets.us/.  He's a super nice guy and he has the templates to do the CB360.  Once you figure out what you need, he'll make them up.  Turn-around is very reasonable.  Usually, within a week from order you have them in your hands.  Key to using copper gaskets is a proper temper.  Some will argue that the best headgasket is MULTI LAYER STEEL (MLS).  Cometic can custom make them for you, if they are not in stock.  A combination of a copper base and MLS head gasket would not be a bad way to go.  That said, I'm running copper base and head gasket on my 378.

Yes Irk did and also thinking way back CrazyPJ did it too.

This was mine. I did it because the engine case stuck out more on this side and it seamed right. That was until I got to put the kicker on

I think the look is worth altering to kicker to make work.

Ooo thats a really nice job. :)

Adding a couple small heat shields will make all the difference.

I made mine from some thin stainless and hose clamps.  Not too pretty, just effective.
