Yes, my dished pistons in my 81 EK came up very high.
Technically the EL and EK blocks are the same - the extra displacement of the EK (1751) over the EL's 1600 is from Honda basically stroking the EL motor to give it a longer stroke. Looks like they used dished pistons to drive the compression down to the 8.8:1. My 81 EL has the flat pistons and I recall exploring this as an option too. I do not have the numbers handy but the flat pistons in an EK would drive the compression very, very high. I also wonder about some issues with valve clearance with my larger valves.
I should add though that my head had some work done that would have risen compression anyway, so it may not apply. I am running about 10.6:1 and that may have just been raised now that the machine shop had to plane my head down a bit after blowing the head gasket.
PS - John, got the studs in and torqued down today
