Sealant slows the heat flow ...( on my Enfield and CR I dont use head gaskets ,,, just a lapped surface ,,,)
If you are worried about the flatness of the head , you can run a smear of sealant ...though place the sealant back from the edge as it is a lube i.e slippery and the casket can tend to seep out into chambers ....
Please becareful when using a torque wrench on cam cap bolts .... the threads that the bolts go into ,,can strip v easily ....
One final thing Dont use sellleys no more nails ...I had an old hilman avenger,,I couldnt be arsed fixing the head ,,,,so I threw away the head gaskets ,,,,applied a ton of no more nails ,,,,,Work ...its was tight as a gnats chuff...so tight in fact that a year later ,,,when I decided to keep the ole girl going a bit longer ,,,,I had to remove all the head bolt and use a bottle jack off the firewall the break the seal ......Damn good stuff that selleys no more nails ...wonder what else its good for.......
