Getting to the point of rebuilding my XE. It is just going to be a standard engine as I will be fitting a LET in the future so just cleaning it all up and refreshing the engine.

So I have a coscast head and when I removed it there was a slight leak on the headgasket between the middle 2 cylinders. I have always been of the view that if you take a head off you get a light skim to be sure. However looking on the internet there seems to be conflicting opinion that on a XE it can do more harm than good.

So what is the view on here, skim or not? Plus can I be lazy and leave the valve in as they are not flush with the face of the head lol

Only every get it skimmed if it needs it. It is also possible that your problem could be the block, especially if it's been cooked at some stage.

I dont have a problem as such, I only stripped it as I had loads of time and wanted to check it all out. I will prob get the block face checked too though to be sure

BTW you can get the head skimmed with valves in place as they are not flush with the head, some places may get funny though

Get it checked with the bloke in front of you... Or they will always skim as it is a lovely cash cow.
