Degreeing a Cam Shaft

wow you guys are really quick, holy hell. lol So after I had a swig of Jack and Coke I thought of how this car is using hydraulic lifters and that by contacting the back of the rocker arm at the point right above the push rod I was not accounting for the collapsing of the hydraulic lifter since they are not pressurized. Which I guess since I dont have a solid lifter or a fancy lifter bore tool, I will have to remove the intake to be able to contact the edge of the lifter with my dial indicator. Which I didnt want to do, but given the tools I have I dont have any other way. Thank you! Ill keep everyone posted on what I find.
