What comp were you after? 10.5's are available at a high cost from US. I am about to source the same via wilkins at Seven Hills Sydney. So far they havce been great with their recomendations. 9.7's should be available and will be where I'm leaning

A choice but more than on source I have read has noted that the rg head doesn't like more than 1mm taken off. Wilkins can only get forged ($1400/set  ) so thats out. Do you have a pistin out, I need specs and a sample of an original for JP's in Adelaide to try to match one of theirs or make some.

40thou off the head isn't too bad to start...
or just go a 0 deck or 20thou deck height on the block... even more comp... but you must be careful no to raise the comp too much doing that.
hight comp pistons..... $$$ $ $$$ eeek
