I would assume 94.5, the "b" piston refers to the pin height used for stoker cranks

Yeah I thought so too BUT, see this link: https://www.geneberg.com/article.php?ArticleID=163

GB 010 90.5mm Cima/Mahle forged aluminium, 69mm stroke, (standard 39.6mm pin height). These are thick wall with cylinder sizes the same as standard 92mm, case 96mm

and

GB 012D ** 90.5mm Berg/Cima/Mahle forged aluminium, specials 82/84mm stroke (33.93mm pin height) case 94.4mm, head 97mm, 8mm thick crown. Special Dykes top ring configuration for race applications only. 132mm long cylinder and 66mm long piston skirt for proper alignment with up to 86mm stroke travel. RW: 1.0x1.5/2/4.

Today I machined my crankcase for sand seal since the hole for pulley was in a bad shape because a pulley cracked last year and made deep scratches to the case. Now it's like brand new

Started planning my custom exhaust manifold. 3D printed a bunch of different radius bend pieces and different lenght straights to make a prototype which I'll turn into stainless steel header later on.
Trying to fit everything on the stock body without any cutting.
Also want to have a good muffler setup so it'll be a tight fit
