You should replace all of the plastic timing guide rails, the chain tensioner, and chain of course. Machine shop work on resurfacing the two heads came to $500. I spent another $50 on the advice of the machine shop to have the cams polished. Have the shop look at the rocker arms. Mine were worn and needed replacing. Valve guides might need to be replaced also. You'll need valve seals and oiler kits for the cam. All in all, I spent about $3k in labor and another $800 in parts for the job. Well worth it.

I'm ready to put my 380se back together. would some who has done this work please review the following for correct sequence, accuracy, and omissions?
Crank at TDC which means #1 piston at top of crank throw with harmonic balancer mark at zero.
Heads placed without cam towers, cams placed with washer marks and tower marks aligned.
Heads bolted (proper sequence and torque)
Chain placed on left head's cam pully then chain placed on right head with both chain ends on intake side of right head's cam pully.
install tensioner guide then crimp chain. (i don't have a master link crimper, can this be done withouta crimper?
Install tensioner after pumping it up with oil
Adjust lifters or what ever they are called. How are these things adjusted?
put the rest of the junk back on the engine.
By the way, to save from guessing the whereabouts of this other stuff I bought another car with a 380 engine which will help me locate put things back in order.
Thank you all for your consideration,
Dan
