I use water wetter and plain water. The tracks here don't check to see what coolant you run as they use torches to dry the track. But they also require you to run a puke/overflow tank regardless.
The !@&#@(! thin Mopar head gaskets are on "national backorder", nobody I've called has any in stock. The engine guy thinks he knows of a source that may have them so he's gonna give that a try. If not I guess I'm back to the Fel-Pro's.
I use the mr gasket 1120s since they will fit a larger bore but not as big as the felpros 4.180,they are .028 compressed with a 4.140 bore,heres a link.http://store.summitracing.com/partdetail.asp?part=MRG-1121&autoview=sku
That's exactly what I ordered. I'm pretty sure they're the same as the Mopar gaskets (which aren't Mopar, there's another name stamped on them). Even the bore is the same. So the Mopars are 4.140 or the Mr. Gaskets are 4.060. I didn't measure them so I don't know for sure.
The Mr Gasket one I had were 4.060 bore. I think the Mopar perf. thin ones were also 4.060 but they were quite differently made. Slight difference in thickness too. I don't know for sure but the Mopar gaskets look just like Victor gaskets which I haven't had much luck with unless everything was freshly milled. (Block and heads) Had alot better luck with Felpro here.
Good luck Mikel
I dont know which gaskets your reffering to but these are the only thin gaskets Im aware of from mr. gasket and they are advertised at 4.140 bore size.The actual measurement is right around 4.150 bore size,you can see in the pic its a little larger than my caliper-these also measure .032-.035 for thickness out of the wrapper,the mopar gaskets are different like you stated.
I don't know the number on them either. They came in a kit I bought a couple of yrs. ago that I didn't use. I looked all over them and couldn't find a number. When I bought them the salesman told me they were they were the thin ones so that's what I was going by. I measured the thickness and they measured .044 out of the package so I'm not sure how much that would compress to but I doubt they will go all the way down in the .020's like he told me. The bore is also bigger than I was told. I measured them at 4.078-4.081 Sorry about the misinformation. I should have measured them before I spoke. I also should know better than take a salesman's word as gospel.:bootysha:
