hmm righto, its a lot more complicated than I thought i would be, but then it always is.

I dont have the paperwork with me right now ( I am at work doh!) and wont be home for a while. From memory the block was shaved a little to level the boy out, then a 1mm shim has been installed to bring the compression back down to 8.8:1. Will have to do some more research into this, or perhaps I should just order them, fit em, and sit back and enjoy. The change from 1.5 to 1.55 ratio is not much extra lift and I already have a 1mm shim and the extra lift isnt too much.

hmmm.....
