We ran out of things to talk about in my house, so I decided to bury myself i the garage and dig into my 1980 FJ40. One thing led to another and now the body is off and I'm digging into the engine a bit. I removed the I/E manifold this weekend and noticed there was only 1 stud in the engin block. The balance were bolts. Needless to say this made it a royal PITA to install a new head gasket. I leanred my lesson to always order 2 of those suckers. Anyway, I tried to verify the amount of studs that were stock in this engine. I found it's either the 2 ea. center or all top 4 ea. Can anyone clarify for me? Much appreciated
