Are you sure the timing components were reinstalled properly? Except for
the power issue, sounds like you might be off a tooth. You should not
experience excessive heat just because of a new rebuild. I have rebuilt
severla engine recently and do not experience heat problems at all.
Something is wrong and I think it's timing related.
