I am rebuilding my engine, had to go 40 over on the pistons and purchased a high flow head from Turner. Which head gasket should I purchase. Also do the metal ones have different thicknesses like the composite? I don’t have the engine back from the machine shop yet, so I have yet to measure with the dial gauge. If I do go metal I acquired a Victor Reinz, is that a good brand?

Block is original, the head is brand new as mentioned above. It’s a complete rebuild on a 300Tdi, also as mentioned above. Lots of new parts including head bolts.

The method of gasket selection based on piston protrusion is the same across all brands and gasket types. It's in the workshop manual and also covers warpage. However, brands such as Victor Reinz, who offers MLS gaskets, come with instructions that specify max warpage. MLS and composite gaskets share the same part numbers. You need to look at a pic of the product to determine what you're buying.

As a driveway enthusiast, I have used both on different 300tdi’s. The machine shop suggested the metal version and that’s what went in. The composite version that came out showed signs of being pinched. 2 years old and installed pre import. Use what you’re comfortable with.

If you are using a turner head, why don't you get the head gasket they sell? I also got a high-performance head from turner for the 2.8 tdi we are doing and just got a new head gasket they suggested.

I may just do that, as stated above, I haven’t measured the piston height yet since the machine shop isn’t finished yet. I also have 2 head gaskets at the house already. One 3 hole composite and a 2 hole metal.

Time for an update, not a good one either. I did the measurements on the piston protrusion, I had to go with a 3 hole gasket. I was in a time crunch and I had a composite 3hole on hand, so I installed that one. Fast forward to now, I ran the truck 700 miles, ran great, even took it on a 2 hour drive on the hwy, no issues. A day later I drove it to work, which is 25 miles. No issues again. Temp running about 190-195F. Leaving work, I check the coolant level, and I check the oil level. All good. Take off, drive 5 miles on the highway, and I look down and my temp gauge is at 220F. I immediately turn the engine off and coast to a stop. Get a tow home, check it all, found some hoses not tight, bleed air, drive again. No issues, stop for about 20 minutes to clean up. Restart the truck, same thing, get less than a mile down the road, 220F. Truck is airlocking. I have to bleed the radiator, and all is back to normal. I haven't had a chance to do a pressure test, that will happen in about a week when I have time. I am concerned it's actually a head gasket failure. Is this possible after only 700 miles?

With 220 temps absolutely. Have one here where we put a freshly surfaced & rebuilt head on last March. Truck went from Virginia to Texas and the to North Dakota back to East coast and has about 7k on it in 10mos. Gasket or head let go on I 85 in Nc. Haven’t pulled it down yet but blown so bad we had to pull #4 glow plug to release hydrolock.

I have used both versions of head gaskets on 300tdi projects. Side by side comparison was that I preferred the metal set up vs the composite. The bolts torqued up easier and I am bias towards using the metal version. Almost 20k on it since head overhaul and no issues to report.

Cooling jacket corrosion is pretty common.
As long as it doesn't extend far enough to get under the gasket border, you'll be fine.

I went with the MLS myself on my 300 Tdi, stock components, no machine shop work. Just cleaned up the head and block very well and installed. That was about two years and 10,000 miles ago.
