My pistons have turned up at long last they arrived yesterday morning!
unpacked them to find that the crowns are now of a dished apperence
they look like they are the oringinal pistons with additional machining done to them!
maybe they where never machined in the first place
things where looking good untill i realised that the cir clips that hold the gudgeon pins in where not re fitted & where missing from the box
pistons where sent to them with con rods fitted so must have had to remove & re-fit them to do the machining hence forgot to re-fit cir clips
phoned them with-in an hour of recieving good said "sorry" for leaving clips out would send a new set out asap yesterday still waiting for them over a day later
lets hope they turn up for the weekend or they maybe have a unhappy phone call!
anyway i am still smiling

just
will be re-fitting them to make sure they are ok before i re-fit the head!!!
thanks for all your input & help guys
