Obviously your head/machine shop is familiar with these Toyota heads. I don't see anything in your write-up wrt setting timing or valve clearances. When I did the head gasket on my 93, the job was spaced over a relatively long period of time. When I finally got to starting it, it ran like absolute poop. I traced the issue to valve clearances which were all significantly out of spec. My shop was clearly NOT familiar with these motors and was no longer even in business. So I gathered up a large supply of the OEM shims and proceeded to perform a complete valve adjustment as well as setting proper timing once everything was together. Just wondering, have you or others faced this issue before? I didn't even think to check the clearances when I got the head back from that shop.
Beautiful job by the way. I have 2 93's and one of them looked slightly worse than yours when I bought it for sub $5k many years ago. But it runs well and is triple locked with full float rear so a good project for someone. Not for me since the other one has the same mechanicals in a much nicer package.
