I just can't imagine GM using TTY bolts on anything in the 80s... technologically, they were way behind the curve at that point.
thought the 5.7D used TTY bolts tho? could be wrong..
Oh god... there is a 4.3D sitting in my driveway, with a blown head gasket im assuming..
pressurizes the radiator full of foam, in less than 5 miles..
Pics or it didn't happen!!

I agree - I would be utterly amazed if GM used TTY head bolts in the 80's. That kind of technology was way beyond their level of practice at that time.
