I am right there with 56er on a street 292 build, except I am using hydraulic lifters with Comps roller tip rockers, and assume 56er is using solid lifters? Not to hijack, but I am measuring for pushrods too. If the hydraulic lifters have been soaked in oil, will they stay "up" during engine rotation by hand and give me an accurate indication of valve stem contact, or will they collapse when load is applied? It looks like a 11.70 pushrod length gives me a great contact area centered in the valve stem tip. I have heard of taken the lifter apart and disabling it, thus making it solid for the purposes of these measurements- but then don't you have to add additional length (.020?) for pre-load of the hydraulics?; thats something I have no experience in. advice?
thanks, Tad
