77 CB750K Pistons Work in 76 K?

This post was updated on .
Hello, I have to rebuild my top end since the motor was seized in my 1976 CB750K and one piston was broken upon tear down. I am watching a pair of jugs and pistons from a 77 CB750K. The pistons for the 76 K have flat tops, but the 77 K's are slightly domed. Would the 77 pistons work with the stock 76 head? I know ring spacings are different and I would have to get 77 rings etc, but I am worried about squish clearance etc. Thanks!

If the pistons are domed they are probably from an F model. Would not work with a K head.
Why don't, you try this? http://www.ebay.com/itm/69-77-HONDA-CB750K-PISTON-BIGBORE-65mm-SET-GASKET-/130643718718?_trksid=p4340.m185&_trkparms=algo%3DSIC.NPJS%26its%3DI%26itu%3DUA%26otn%3D5%26pmod%3D140577656369%26ps%3D63%26clkid%3D6953495943195232130

The mating surface above the chain tensioner on the cylinders got bent downwards and I am afraid that it will leak oil, so I was going to get new jugs completely. Also, I don't think I could afford to have it professionally bored out.. That answers my question about the pistons though, I know the F's prior to 77 had the same pisons as the K's for 77-78 so..
