Gaskets or Gasket Maker?

OK, so looking for a few opinions. I have to reassemble the 100 Engine and have had better luck with using Permatex® Ultra
Copper® High- Temp RTV Silicone Gasket Maker over using the paper gaskets often included in the rebuild kits.

Thoughts on using Gasket Maker over actual gaskets with the typical gasket sealers?
 
I've always used the included (paper or otherwise) gaskets included in head & conversion sets.

I usually supplement the gasket with something like this though; remember, you only need the thinnest of "smear" to do the job (I just don't get it when they say to put a 1/4" bead on the flange__you wind up with an 1/8" bead on the outside of each side of the flange!).

We have had good luck w/the Dennis Welch head gasket and they also make head bolts that are Whitworth thread on the block side.Not cheap,but worth it.Welch is well known for racing parts,they also make a heavy duty rear spring set that we have installed for our customers,check them out...
 
I used all the paper gaskets and Hylomar HPF gasket dressing. This compound is hard, if not impossible to find in the US at this point. Do a search for "gasket dressing" and youl'll come up with several threads about it. It is great stuff. It stays flexible and comes in spray or brush. I found some of the spray on a dusty shelf corner in a Napa store. I have torn down a few engines over the years where I found pieces of silicone sealer where it shouldn't have been. The Hylomar allows you to put the gasket in place, but still move it slightly. It doesn't seem to ever harden, so makes removal easier than dried out permatex or silicone. The latter can be a real bear to remove if you need to. I had a heck of a time trying to seal the side shift cover on my gearbox until I used Hylomar. Some folks think the job of oil is lubrication and cooling, but we have recently discovered that it's real job is to somehow find it's way out of what ever you put it in. It can take years, but it is nothing if not persistent. I have been happy with the paper gaskets.
 
Mark,
Thanks. I never would have thought to look at Harbor Freight. Oh great, just one more thing I MUST HAVE at that place.
 
Thanks, I'll use some dressing or flange sealant with the gaskets supplied. I'm using a DWM head gasket and head stud kit. Seems to work really well.

I'm also going to use a DWM Oil Pan, should be good for a better seal than the OEM pan.

Michael.
