Yes. 'We'(One Woman((Me..)),and 4 old Men,PLUS 'various other old Gezzers' who were roaming around the Shop Complex. In all,there was about 16 of us in there. And YES we used the 'hold the Valve with Compressed Air method.' In all,it took about 4 hours,taking our time with everything. The only 'bad' thing was the crappy Valve Spring Compresser Tool we used....luckily,we had a better one on the Shelf :wrench: 8) . 'Our' next little 'project' will be the Timing Chain in my '69 Buick Le-Saber. Fun. Fun. Fun. ~OO6.
