Nice job John... feels good accomplishing something like that eh? Something about that DIY feeling that you can't really explain to the non-DIY'er.
BTW, perfomanceproducts.com sells a "TDC whistle" that you place in the spark plug hole. When it stops whistlin' as you're cranking you know you've reached TDC on that cylinder. Might come in handy for others thinking about tackling this type of job.
