Cheers Rich, I did reply to myself but dunno where it went. Basically I
found a bit of info on the Rpi site which pointed out that if you fit them
wrongly you actually loose 40% of power due to blocking up half the exhaust
ports. Once I took a good look both sides were the same but there is a notch
on the gasket which matches a notched but on the casting for at least 4 for
the 8 ports.
Just thought it may be helpful for any one else in the same position.
