Time for a survey!   No,  not what tires to run.   Which sealant (goop) do
you swear by when you replace heads on motors YOU build or have built?  I
saw one write up and they advise to NOT use what comes in the gasket set.
Some people say "Right Stuff" is best.   A tube of "Reinzosil" from Victor
Reinz came in my set but, in a similar light, GoWesty states the proper
crank seal does not come in the gasket set but should be tossed and a
different one bought separately.   No wrong answers here and if you have
facts and figures to back up your choice of product, all the better.
Let's avoid the whole, "My best friend's sister's boyfriend's brother's
girlfriend heard from this guy who knows this kid who's going with the girl
who saw some guy use _________."     With that in mind,  not sure what the
"experts" use but as the man says, "Let's get it on!"
