Right, you have Nickies on the ROW's...easier to re build than alusils but you'll still need to do a standard matching process that should be determined by specs and condition.

Have them inspected to ensure that they are within spec. If within spec, you can buy JE pistons.

Most engine builders (on this board) recomend 9.5 c/r.

If cyls are out of spec, replating by EBS would be one route, or, buy another matched set that is in spec.

Don't know if this will help you but, I have a set of 3.2 jugs and pistons from my 87 (I replaced them with LN 3.5's & JE 9.5:1). I'd say the bores need to be replated (typically done for under $1k), the pistons look good. PM if you are interested

The above scenario will probably not help.

1) Easiest; send cyls to EBS for re plating. Buy new 95mm JE's at 9.5 compression.

2) Buy used 3.2 cyls, send to EBS for boring/re plate to 98mm. Buy new JE 98mm pistons. This will create a 3.2 "short stroke". Lots of information on this in the Engine Building Forum.

The 3.2 cyls are more desirable for re plating due to the SC cylinders having too little material between the bore and the sealing ring grooves.

3) There are many options that become $$$ and more complicated
