Hey Crew.
Done a HG on my sierra. What do I need to know to replace it? I have a new gasket here, and I know I'll have to get the head machined and tested before i put it all back together but I've heard that the timing chain needs to be in a certain place before I take it apart and that number 1 needs to be at top dead or something along those lines... Can anybody elaborate on this?
Anybody done it before and want to come do mine? I have all the tools besides a timing light... I can provide grog...
Cheers Myles
