Yes that cam loves 103. To do it in the car I use 1 solid lifter.(a hudraulic moves the plunger too much) A bb adjustable pushrod using the rockers and dial on valve retainer or better a solid lifter pushrod you can put the dial indicator into that. positve piston stop you can buy them or make them out of gutted spark plug and 3/8 threaded rod http://s542.photobucket.com/albums/gg408...pg&newest=1
Best to remove rocker gear before using piston stop. you can leave distributor in and your timing will advance or retard timing the amount you moved cam check then reset timing!
