WOW i doubled that not good, do you guy silicone the acorn nuts?

I've never used silicone for anything just the copper washers that the head came with. I do use just a little vasoline on the orings to hold them in while I'm getting everything together.

i did the vasoline an tourqed it down to 40 psi an antifreeze started to come up around all the head bolts, when i poured it in

Same as mad, no silicone, copper washers and little vaseline.

 

Did you put the little rubber o rings that go around the bolts between the two plates.

psi is a pressure. Look again at what the units are on your torque wrench. Should be n*m or lb*ft or lb*in. It would help if we knew that you were actually torquing them to spec. which is ~20 ft*lbs. You could have also pinched one of the o-rings that is around the studs which would cause it to leak.
