Someone modified those L2355 "six pack" pistons by milling a dish in them...they are normally a 4 valve relief design. I've never seen a dish like that on the "top" side of the piston before, that would ruin any quench you may have had. It's possible whoever machined the pistons put the dish on the wrong side of 4 of them.
It really won't hurt anything, just not the normal way of doing it. grin

Thanks for the insight as far as why they may be that way. I agree, the surface shape totally messed with the quench, You are correct the pistons are facing the correct way in the engine. No idea what the thinking was behind this but what began as a quick cam correction is snowballing into a full blown overhaul.

I got way too many projects to add to my list LOL oh well, here we go!
