In regards to the RTV or FIPG to use, I recommend you go with the Toyota 103 FIPG (black) The red FIPG is for transmission, transfer cases and differentials. Don't do what the write-up suggests and put a huge bead of RTV on the heads. That is totally unnecessary. Ramon did a great job on his write-up for this job, but his application of FIPG was pretty ridiculous and way overkill. You only need to put it over the half moon junctures and in the corners of the cam humps. You also need to put some onto the cam plug collars when installing the new cam plugs. The cam plugs Do Not require FIPG on them like some guys do. The cam plugs have a rubberized outer surface and that makes a seal with the head and collar just fine. Adding FIPG to the cam plugs is just going to make it a nightmare to clean out the old FIPG at the back of the heads if you ever have to perform this job again. Good luck!
