[FC] head gkts

[Ken Hand]

As always there is never a single defining answer to a question. It all depends on what you are trying to do with the engine. As far as copper vs. stock steel; with the copper you do have more choices of thickness but I have found in my personal experience that the copper ones will tend to burn long before the steel ones do. My race car was not street use but I did use copper gaskets on a couple of engines and when I took it apart there was evidence of hot spots and even leakage past the gasket. On all the engines that I used the steel gaskets on there never was any evidence of leakage, even when the engine was overheated.

This may go against all proper thought but if you want to get rid of spark knock or at least slow it down take .030" off the gasket surface and use the stock steel or .032" gaskets. This will give a better quench area and deter any spark knock, even though it raises the compression.

The reason I say take off .030" on the gasket surface is, if you take any more off you will have to mill the face of the head also because of the cylinder shoulder interfering on that surface.

Good evening everyone
I have a question concerning head gkts, you talk to one person, supplier etc, 
se copper, other says use steel , other says alum, other person says use 32" 
ther person says use 20" (thickness) some say using 20"s head gkt you raise the 
ompression to high, I have been told put cyl down on flat know surface, see if 
ou have more then 2" between top of cyl to surface, if you do get rid of cyl.. 
t present this is in regards of a 110 Eng. at present the heads and cyls are as 
e took them apart nothing has been done to them yet.
Please someone I really need some guidance...
