I don't think I'll be able to hack making another set of those head bolts any time soon and getting the plug leads lined up is turning into an almost as tremendous headache, so I don't think I'll be going anywhere near this level of detail again any time soon - or rather if I do, must remember, make engine first, then build bodyshell around engine... and that right there would be the benifits of forwards planning, of which none whatsoever has been involved in this build.
