Afternoon


Had my JP4 head skimmed for use on a J4 block.
For now, I'm planning on running it n/a just to let any problems worm their way out.

Am I correct in thinking I need to use the JP4 haedgasket for clearance?
Also, when I had it skimmed the bloke didn't give me a measurement he just described it as a 'light skim'


Therefore I have various queries...

A) Will I get away with one headgasket
B) Will it run okay if I double them up now in anticipation for turbo time, or will this cause more harm than good and is generally frowned upon? I'm sure people have got away with half a bar on double gaskets?


Thanks guys
