The head came off the 86 this weekend after blowing the gasket so it's time to take the head to be machined.
So long as its going to get machined I figure it may aswell get a few extra thou skimmed off to give a bit more kick.
How much do you think should be taken off to give good comp but still give a lift in compression? It will most likely be using a .8mm trd metal head gasket.
Cheers.
