I am not a guru RisingSun but I do have a GREAT DEAL of EXPERIENCE with FPR changes LOL. The fine art is to use a 10mm ratchet spanner for top 2 bolts and A LONG socket to get to the third bolt from underneath. You will work it out after a lot of swearing .... It takes about 20 mins now.
The reason I am SO experiened is that when I did my head the only gasket that wasn't in the kit was the FPR (and for good reason as I found out). Firstly, I went with the old gasket... Wrong! Next... I purchased a new one... Great work guys.. It was the wrong gasket because the FPR has been modified a few times by design. Despite quoting VIN I still got the wrong gasket. I did check here before fitting and I did get some advice that both gaskets would do the trick.. WRONG! Desclaimers accepts guys LOL.
After much discussion with Brabagellos here in Perth I managed to get the right gasket ordered in. Thank God someone in parts knew what he was talking about.
