I installed my new AA piston in my type 2 bus engine yesterday and was wondering if it matters how the pistons are oriented in the cylinders? I guess I have a 50/50 shot of getting it right! Any thoughts? Thanks

QUOTE(Montreal914 @ Jun 29 2020, 11:25 PM)  Yes, the valves angle upwards, so you're upside down. These are aftermarket pistons intended for cams with more than stock lift. Both intake & exhaust are side by side, not hemi like as in Porsche 6 cylinder heads |
