Hey guys i have a set 81mm 9.0:1 pistons for a b18c1 and was just wondering if you guys could tell me how to allign the pistons to the front of the engine. usually there should be some sort of marking on any piston, stock or aftermarket i.e. dot etc.. well in this case, i cant to find any. so if there's anyone out there that worked with one of these before, your help is much appreciated. thanks!

 

any idea?

 

hit up the company and ask if they have any papers for them or read them if you got some with the package?

 

Which side of the piston has the larger valve reliefs should the side with the larger valves...guess which that side is?
