So I have been working on swapping the heads on my 95 to the 96 style heads, got everything back together and started it tonight only to find the passenger side head leaking. I know I am going to have to take everything back apart to figure out why it is leaking but am I going to need a new gasket set? I also did read after I got everything back together that you need to purchase new head bolts when you pull the heads off, could this be why? I am more than frustrated and am completely out of patients so my question is do I need to take the head back off or should I just try to take the valve cover off and try to re-tighten the head bolts? And if that doesn't work will I need to buy a new gasket set and new bolts? Any input would be fantastic because at this point I am ready to take it to the scrap yard and junk it.
