Completed the job,engine runs better than ever!
It was scarey when I started her up, very noisy valve lifters for a short time, missing badly, backfires, check engine light and she started to run hot. She settled down nicely and ran beautifully after I discovered I had mixed up two ignition coils and the brand new thermostat stuck closed.

I have not yet installed the timing belt cover, top ignition coils cover, belly pan and few other items. I plan to drive it around neighbohood with few short hops on the interstate for a few days to put it through a few heat up/cool down cycles while checking for any oil or coolant leaks. Then I will change the oil, filter and coolant and button her up,.

Thanks for the information, advice and encouragement from fellow Bricksters. I can say this is not a job for the faint of heart but quite doable with meticulous care, patience and planning. I was able to complete it without any of the special Volvo tools. I did order the engine manual from Volvo though. If anyone is thinking of removing a head on the B6304 engine I would be happy to offer up my experience. There are some procedures in the manual which can be done much easier with no ill effects and a few gotchas.

By the way when I went to install the new serpantine belt it was too long so I put on the old one. I seem to remember something about an alternate method to route the belt around the pulleys possibly to give more grip on the alternator. Anyone ever heard of this? Otherwise I have the wrong belt.

Thanks again
