[QUOTE="kleake, post: 1399376, member: 25987"] Verified--- #4 and #6 are actually holding 360psi on compression. #2 is at 360 with an old rocker, but at 0 with a new rocker. #8 is at 360 if I just bust off the torque on the bolts, but is at 120 if fully torqued down. What makes this really weird, if #2 and #8 are the issue on this side, and by the sound of it cranking, all cyl that are missing are in sequence, per firing order (1-2-7-3-4-5-6-8) that would mean that it must be cyl 8, 1, 2, and 7 that are causing the issue. Now,,, the interesting part is that is the front two and the rear two cylinders.... Front valve on #2, rear valve on #8. I don't know about the right side, but it may be the same. Is the head flexing on the ends? I know, i'm getting pretty scientific about this, but I want to know what the issue really is before I go tearing in any deeper. So far it seems I could either use my old rockers or modify the new ones and be fine. I know that isn't really the best option, but it would work and likely be fine. [/QUOTE]
