It is a common mod, and Yoshimura even sells the damned gasket
Fuck engineers make things far more difficult than they need to be.
When I said it was an interference engine was when you were asking about OPEN valves and timing changes iirc. . Your fault if you spoke incorrectly.
When I said near zero, I mentioned blueprinted engines as well. Stock they are damn close, but not so close as to not be able to use a thinner gasket. But AGAIN I say it will almost certainly require high octane fuel (not just premium) if you get one. For street use it is a ridiculous mod to make on its own since it will gain nearly nothing honestly.
Dude. You are one dense motherfucker.
Let me guess. Engineer? Some of the most dense fuckers I have ever dealt with are almost always engineers. Dumbest smart people on the planet.
That is not to say all engineers are dumb. Just most of the people I deal with who THINK they are smart, but really arent, turn out to be engineers.
I dont claim to be an engineer, a machinest, or a master mechanic
what I am is a guy who has a bunch of years working on them, riding them, tuning them, and being involved in them.
I know what people do, what can be done, what it takes to do it for the most mart, what is worth the money and time to do so, and what is not.
Do I know the finer points of high end engine building? Nope. That is what I pay Livengood Motorsports to do.
But I DO know that the shit you want to do is pointless unless you do it in conjunction with a heap of other things to be able to realize any gains, and not mostly loses in other ways
