J spec 2F?

[d55guy]

I just picked up a 2F engine from a guy who did a BB V8 swap. Tonight I stripped it down to get ready for a rebuild and I noticed the valve cover had unusual stickers. The 2F sticker is red instead of blue and has a bunch of japanese characters below the 2F. There is also another sticker on the valve cover with some japanese characters(sorry my digital camera is down). Is this a J spec 2F? If so, are there any differences between the USA 2F and a Japanese 2F I should know about?

Thx,
Kerry

I have some J spec valve cover decals that I bought from the dealer years back. I even put some on customer's engines that I worked on in the shop. Sooo, I wouldn't jump to the conclusion that you were dealing with a true J spec 2F.

When I imported J spec 2Fs, the most distinguishing feature was that the 2F cylinder heads on these motors did not have the air injection ports. Not just plugged. Non-existant. Does your head have the injection ports?

It has the air injection ports so it's not J-spec. Thanx for the info.
