Such a good guide that ^^^ Its not too difficult mate. Its all about taking your time and cleaning everything to perfectiong before refitting. Your going forged so you need a bit of machine work anyway. I learnt this the hard way, should of got my bores and tolerances checked before rebuilding mine. So yea throwing a forged engine together wouldnt be too difficult when teh machine work is done and other used compnnents are clean.
