Question about 1997 GMC Sierra
Hello dysone...Is this a 5.7 litre engine?...Why were the heads replaced on this engine? Did it overheat and crack one..or blow a head gasket? Were BOTH heads replaced, or just one? How many miles does the engine have on it? Yes, you could have damaged some valve train componets if you over-tightened the rockers. Possible bent pushrods, collapsed lifters, or even bent a valve.
Did you check the engine block for warpage..was the deck straight and true?
Were the new heads properly torqued when installed? Did you reuse the old head bolts or replace them? Many factors to consider here...If you can tell me a little more i may be able to provide you with more answers.
Good luck...i hope this helps.
