Nice one chaps, i’ll give Mr Pepper some money at the end of the week!

whas the pros and cons of copper vs mls then?

For turbo's and competition bikes that have very high cylinder pressures, the copper gaskets are more forgiving (IMO) and re-usable. The block liners have a wire o-ring inserted which 'bites' into the copper gasket producing an exceptionally tight seal. Come to re-use time you just re-anneal the copper, making it soft again and it's ready to go - good as new. Copper is good for air and oil cooled engines - MLS is better for water cooled, although good for use with road and mildly tuned air / oil cooled motors - personally I wouldn't use one with a turbo or a big, big bore where bore to bore  (1-2) and (3-4) metal surface is minimal to provide sufficient clamping pressure making blown gaskets more easily possible.

Ran MLS on mine as well dave with no issues,running about 190bhp at 11psi , o ringed and copper head gasket now on the new turbo kit because we are going for more horsepower.
