To catch everyone up on my situation: the '74 TR6 I bought was a non-runner due to a broken off spark plug. I took off the head, sent it to the machine shop. It checked out fine for flatness, so was not milled. (The valves also tested out good...so after removing and retapping the plug holes, I got it back.)
When I reassembled with a new head gasket, I wound up bending a pushrod and breaking the rocker arm closest to the firewall (#6 cyl) because the pushrod seemed too long. I just got new pushrods and a replacement rocker, and even adjusted totally out, it is still too long. The gap between the rocker shaft support and the head with no bolt on is maybe 2-2.5 cm.
Has anyone ever heard of such a thing? Remember, no mods were made to the head or block between remove and refitting except for a new head gasket, which appeared to be the same thickness. Only one pushrod is too long -- the last one. I checked in there with a light and magnet and it doesn't appear that anything is in there blocking the pushrod from seating.
I'm at a total loss for where to go next. Anyone have gone through a similar experience? I'm all ears, since I don't want to break any additional parts.
