That's why I was careful to ensure I noted the correct orientation of the Con-Rd Piston Interface AND their relationship to the CRANKshaft. There is an arrow on the top of the new ones much the same as the old. Those arrows point towards the Timing/Front end of the Engine when fitted. Not all K-Series engines are transversely located.

From memory some pistons I've worked on have different sized Cut Outs for the Inlet and Exhaust Valve clearances. Again from memory, they appear the same with these K-Series Pistons I'm currently working on.

Have you compared the piston ring land areas of the old to new, be interesting to establish a measurement?
I cannot do that now as the new Pistons are on their way to Lancashire. Here is a picture of one of the new ones. As previously posted, I could not see any differences between old and new.... visually.



.... and it is STILL raining and cooler than last week. I'm off to pray towards the Weather Gods..
