I have a receipt for the ross racing pistons. Remember it was rebuilt before I bought it. I had a conversation with the previous owner and it was a cash in hand build by a mechanic. I've been told the head gastek is a toyota item.
I've heard a lot of people on this forum with head gasket issues using a variety of performance gaskets, it seems toyota on the whole may be the best choice.
The engine runs very solidly with no issues or cause for concern. Price reduced to £900 now chaps, my wife wants my car off the drive
