Hello , I just came home with a GM 5.3 Reman. Long block engine and it has a 243 head and a 799 head , Is this common ?

Not really "common", but it's nothing out of the ordinary or harmful in any way. Some came from the factory with two different numbered heads. They're the same heads, though.

Thank You so much Chris for your quick reply and a peace of mind knowing that my new engine is not as strange as I first thought . Thank You ~ Jim

Yep, same head. Many trucks came with both in the earlier years, no difference between them other than the casting number.

My Tacoma has one head from Mexico and the other from Canada, not sure which is worse

whats the specs on the reman? do you know if its been bored out or if the crank has been machined down at all? Curious how the newer engines are done.
