1st can we keep this topic interesting as i don't think we have had a full on debate on his subject
Ok karl as i work on Motrocycle Engines and have vast experance with head gaskets and surface finish can you please advise on type of finish req for the Head being Aloy and the Block being Cast iron ?
Why i ask is i have a Small turbo Escos that i will be doin the Head gasket on soon and sometime plan to change the turbo to gain 350-370 BHP
Also can the wire ring be installed with the Engine in still in the car assuming the surface finish if ok.
Thanks in advace for your input
