head job gone bad
my 91 toyota 3vze had a burned valve. i had another engine i removed the heads and delivered them to the cylinder head shop.when i picked them up he did all the usual and set the valve lashings.when i reassembled my engine the it ran like crap. (i.e would not idle, backfire through the intake). i triple checked my timing and its perfect.my muffler ig getting extremly hot at idle.what could it be.

Stuck intake valve? Have you checked compression? Not too familiar with the 3vze but is the timing belts setup correctly on the pulleys? If it was me, I'd double check that stuff first. Good luck.

Check the timing belt and distributor timing (firing order and advance) again to ensure you didn't miss something.

bloops! i've made that type of blunder before. after i swapped in my 20R head, i fired it up and it ran like total crap. yanked out the timing light and it was a *little* off but setting it to spec didn't help.
ended up, i noticed that i had forgotten to connect my brake booster line. doh!
