205 Low Compression on Cylinder 1

Didn't know whether it was the DFW or the J4Zs that were hard to come by. In any case I have a few of the J4Zs if anyone is after them plus the high comp Wossners with liners.
 
The weight saving sounds good I will keep it in mind. I noticed that the DFW pistons have cut outs for the valves, does the swish volume change much from DFZ pistons with DKZ head configuration I have now?
 
The DFW piston sits 1.2mm down the bore, so that's 6.5cc. Then add 3cc for valve pockets, for a total of 9.5cc. Thus just a fraction more than the 9cc of a DFZ piston.
