"Skim the head a little more" means take it to a machine shop and have the gasket surface milled flat, required to repair any head gasket issue. While they are milling, ask them to remove more material.

But, you can only take the milling so far before you begin to change engine's timing/intake alignment etc, etc..

What upper engine parts? Are you going to spend the $$ for custom pistons, a re-balenced crank, custom knife edged rods, Ti valves and keepers.. I need more to go on the upper engine parts.

I can have the guy skim it more while he pressure tests it but how much more should I tell him to. As for upper engine parts I think I will pass as it seems like too much is involved. I was thinking about it if not too much was involved but that doesnt seem like the case.

Vcci, the normal amount milled off a head is .008-.010". However on some heads we remove .025-.030", for that little increase in compression. Your machine shop can tell you what is safe. The difference is slight at best. I have no experience with your motor, so I won't hazard a guess. Milling large amounts off the head, on a motor with a chain driven overhead camshaft, will change the cam timing.

If your machinest doesn't know how far he can go on this engine you have your heads w/ the wrong machinist.. I send all my blocks/heads/cranks..you name it to a guy on Long Island. We have been using him for over 20 years and he has been supplying us w/ spot on work for all that time.

I would Highly recomend you send what ever it is you are doing to him.
516 741 6579, his name is Joe Getler.

Let him know I sent you and you'll be fine.

BTW, the only cars where 'not much is involved' in modding the engine is a Chevy or Ford.. Anything having to do w/ making a Mercedes go quickly is Always going to involve a lot of time and money!

I will ask the michinist about skimming the heads and by his response I will know if I should let him do it or not. I have been using this guy for quite a while and I know he's been doing this for at least 20 years so I trust he knows what he's doing but if I feel he's not able to skim it correctly I will just have him resurface and pressure test the head and leave it at that as I don't want to cause headaches down the road. I thank you all for helping and will let you know how it went and what I ended up doing.

Anytime you pull the head you might as well replace the valves, valve guides ect.. because of the labor required to remove the head, you don't want to have to do it again later, so you might as well get it all done in one shot. We have had to take the head off two 16Vs and there is just no point in doing all that work and leaving parts that have over 100,000miles on them in the car.
