well, i got the head back today. after i dropped it off yesterday i started feeling sick that i should not have done it.
i found a guy on the net that straightens them. $150 to straighten and $250 to grind the valves. any other parts are extra. so thats really not too bad, i just dont want o tput that much money in this car. i guess its the "ive been putting enough money into it already" syndrome, plus the car is not that nice. but, as some of you may be thinking, it may cost more in the long run.

BTW he took off .014.

i am going to put the cams in the head without the lifters tonight, i hope, and see how it turns, guess i should have done that first. cant believe i have been doing things like this most of my life and i still can do it backwords.

getting the cover off is easy. there are some pry tabs on the sides for lifting it off. some guys use big C clamps to clamp it down when putting it back on. i have had the cover off to replace the rear exhaust seal. i tried to put the seal in first, did not work. i ended up taking it to a volvo friend and he pulled the rear seal and put a new one in, and you know how little room there is back there. to this day, he will not tell me how he did it. only vague answer like you learn tricks, or you make tools to do the job. oh, he only charged $100. if i had just taken to him to begin with i would not be in this situation.

no special tools, the cam holders would be nice. you have to mark the cam sprocket in relation to the cam.
be VERY carefull with the gazzillion bolts that hold the cam cover.

i must say, i am very impressed with the combustion chamber. too bad the 911 was not this good. very compact, pent roof, 4 valves and the plug right in the center.
i dont know if it is true, but i was told porsche designed the motor.
i dont know if all or most water cooled engines are like this, but the cylinders are completely exposed to the water for cooling. also, the oil filter mounts to an oil cool that is cooled by water, the earlier cars had a regular oil cooler mounted up from. things you dont see on everyday family cars.

my plan for putting the cam belt back on is to line the cam marks up, and if the cams need to be moved to get the belt on, due to the cutting of the head, i will losen the cam bolts and move the sprocket.
it does not matter, when i had them out before, i did not know they were adjustable so i had to put the sprocket back on based on the bolt marks.
i also plan to mount the intake and maybe the exhaust before i put the head on. i will have to see when it comes to taking the other head off.
