First off - I just figured out your screen name. DUH on me! :roll: LOL!
Ask away and I'll answer what I can.
No pix yet. I hope to pick them up from the laser cutter the end of this week. They are a direct copy of a stock head gasket, so no changes at all.
Good idea about the larger bores. I wasn't thinking about that at all.
As easy as this stuff is to trim, I believe you can make them fit a larger bore w/o any problems. I would go about it by putting the gasket on top the jug, putting the correct bore diam gasket over that and then use a #11 exacto blade or a small file to open up the bore on the gasket to the correct size.
- to answer #1, you obviously tune to a more precise level than 90% of us. You may notice the changes, while the rest of us won't.
In general the guys that own Pilots tend to jet on the rich side for longevity of the engine, so the minor changes you'd see won't be an issue.
My main reason behind these gaskets is to help out with the guy that has a head that's been cut too much and needs to lower compression. Correct me if I'm wrong, but wouldn't this do just the opposite of question #1?
And, if you have a setup you like, gasket wise, you can just peel these down to the same thickness and not change your tuning at all.
Overall, it's just an optional part for the FL400 that will allow you to drop or raise the compression and the way the engine works with it - what ever your heart desires.
