Look at the TRSM... Basically a small gap between the block and the timing cover (lower). The head, would then sit on top.... Think of the capital letter "T"... The very top would be the head... the stem would be where the block and timing cover would meet.
Exactly where the top of the letter "T" and the stem come together is where the RTV goes... I think on the right side, front/top of the engine as U R facing it.
Hopefully someone's got a pic and can show it better..... The head actually covers both the block and the timing cover.... like the top part of the letter "T."
Sorry I had to Sesame-Street it, but hopefully it'll help someone else.
Good luck!!
