2006 Pilot EX-L Touring. Spark Plug seals, front & Rear cylinder heads. Looking at honda's parts list it is showing two different part numbers for rears, but if I'm correct the diagram is showing the front has a different part number than the rear.

Front: 12342-RYE-004 is replaced from old 12342-P2F-A01

The rear is showing two different part numbers.
12342-P2A-005 (KOYO)
12342-P2F-A01 (NOK) replaced by 12342-RYE-004

For the rear which one do I use? 12342-P2A-005 (KOYO) OR 12342-RYE-004

P.S. Also is there a bottom seal of the spark plug tube? I saw a youtube video of someone pulling them out and using high temp sealant while rebuilding the cams. Can this be an issue of oil in the tubs as well?

The engine code on mine is Engine J35Z1 on my 06 Pilot EX. I ended up having to get Fel-Pro VS50607R-1 because the rear valve cover bent up at the timing belt cover

Find the whole kit on Honda automotive parts.com You don’t need any sealant to put on the gaskets or spark plug tubes. They are designed to lock into the cover.

there is only the main gasket and the 3 spark plug gaskets for each head.
