The only difference is the sleeve..If you fit a 5 port sleeve into the 7 port crankcase ..voila!.. same rod piston crankcase/crank etc..obviously if you change the sleeve you need to fit a new piston etc at the same time..
If nobody wants to buy my MM stage 5 7 port p/r/s I'm goig to keep it and just fit it to my 3 port R when it wears out..mind you once my MG66 arrives I don't think my 3 port will be getting much runtime..
