Ok, here is info on Valco.
Valco Cincinnati Consumer Products.
www.valco-cp.com
Look at bottom of home page to right side, "Where To Buy" for dealers.
Doug Herbert is one and so is Fowler Engines.
Silver Aluminum RTV 3 oz. is part number 71195. Great stuff. Not the same as any GE based silicone RTV.
Other products I use are:
Gellube 71756 Good areosol spray that sticks to metal.
Hylomar Gasket Maker . 2 types. Aerosol is great for copper head gaskets and blue in a tube is good for gaskets too.
Also look at the ENGINE BUILDERS kit assortment 71859
They have a variety of products you might find useful.
Of course the prices are at manufacturers suggested retail and there should be a discount almost anywhere
I buy my Valco at VSI warehouse at a good discount, but you have to be a dealer with them.
One of my customers bought a truck pulling engine from the owner of Valco and he gave us a good supply of products to try out.
