'Competitive engine builder' much better , shows where you are coming from. Standard definition of cylinder block deck height is perpendicular distance between head mounting face and crank centre line. To optimise compression the deck height will need to be altered if and when piston, rod or crank are changed and some of these alterations may involve the use of your 'putting on' machine. Taken with the third attempt at a suitable silencer and by the terms of your kind offer the cost is just about that of a new standard T2 complete. Budget engine class my........ The 'holy grail' of equal engine performance last time was ignition timing, now it is exhaust and/or presumably piston deck height. What's coming next? Well plenty to go at. Head volume, cam form, crank alignment ,port shape and finish,etc etc .So standardise all those at £100 a throw and you may or may not get equal engines ,if that's what you want. Alternatively decide on a mean power output figure get a bach of engines , adjust the performance to standard using the same methods as are now used to maximise output ie. ignition timing , cam timing, alternative restrictors. Then seal the thing. Level playing field. Everybody wants that don't they??????
