Every time I ask them they can't find them in their books, but trust me, they have, I've seen them. They were for a bunch in Tassie, but were for 18rgu head of 1982 vintage. The people who ordered them can't remember ordering them, it was for a client of theirs a few years ago now. I can give you the specs on them if you want. I have that at home. They can also do a 91mm bore with a stock shape dome, to what ever dome height you want. Yes, 11:1 is very high for 98 octane fuel, it will ping its head off. I have heared of a guy who went through many, many head gaskets with 11.5:1 in an 18rg and eventually had to get it decompressed to 10.5:1, now it's OK. If you want knockoff original 9.7:1 pistons, I could do a little running around and I reckon they could do that for you as I have all the critical measurements of those pistons at home. Philmelvin. I made the post about the price and it was $660 GST inc. with cast iron rings and I think with gudgeons(these rings will need to be swapped for chrome ones, which are available from hastings, I have the part numbers for these rings if your interested. EVERYONE PLEASE NOTE: these pistons are CAST, if you're after forgies these are not for you. [Report message to a moderator]
