Having just had a P79 head done with a similiar problem (pitting around one of the water holes).. Unless there is a crack in the head it usually can be repaired. Go to a reputable machine shop that works on aluminum heads. They'll be able to fill the corroded spots and resurface the head. == Glen

Pardon what may be a newbie question. I am rebuilding my daughter's 1981 280zx engine. The block is rebuilt, as is the head. Right now I am at the point where I have put on the timing chain. The replacement chain (from ITM) had the 'silver links', and I lined up the crank mark with the #1 hole on the cam itself and the #1 marker on the gear. My question has to do with how tight the chain should be. After putting on the 2 chain 'guides' and the tensioner there is no play at all. Both guides are tight against the chain itself. Is this normal ? Should I be happy they are tight ? == Glen
