[Fot] Six head gasket?

[Robert Lang]

 Hi - My vote is for venting. Add more vents!!! Oil pushes out because of pressure in the block. Give the pressure somewhere to go and either you get less leaks or no more leaks (depending on the state of the engine).
I think Kas covers this pretty well in one or more of the books.
;-)
By way of example, I run two 1/2" vents in the valve cover and one via the fuel pump blanking plate, so three total. I also run PCV and a Goodparts oil separator. As long as I keep the revs under 6000, the oil getting pushed out seems to be very small indeed, maybe a few teaspoons per session.
There's a common misconception about what gaskets do. They do not relieve pressure and that's why you're pushing oil. Get rid of the positive crank case pressure and "Bob's yter unKle".

 Any head gasket suggestions for gt6 12:1 motor. Have had chronic oil leak at pushrod side of head. Had same problem with two different heads before this one as well. With a different block.  Current Block is zero deck height and head is cut to achieve the 12:1. Just wondering what others might be using for head gasket?Thanks, Brian
