dumb cylinder head gasket question

do i have to use a new cylinder head gasket everytime i take the cylinder head off, or is reusing the same one, assuming its not blown, okay?
 
The head gasket is a one time crush gasket. NOT re-usable.

You could have a solid copper head gasket made that is re-usable, but have more issues sealing oil passages and such....

Are you removing the heads that often?
 
thanks for the info..mydlyf....no im about to bore over .5, took it off to initially re-ring and replace cam guide and tensioner after both snapped into shrapnel, but compression is still terrible. its got 125 compression on both (valves lapped and new STD rings) and still does almost 80 so hopefully with an overbore she'll be cooking. i think the cylinders are out of spec, dont have a micrometer though. but after a hone and new rings i was disappointed with the compression numbers.
i also have an oil leak i believe coming from the gasket itself so either its blown (would that explain the low compression?) or i messed up torquing it down somehow.
can these 360s hit the ton with 17T front sprocket and great compression? i heard they were geared for like 120+mph? i would love to see that kindof power out of this little thing.
 
My cb350 would, but I never got past 95 on the 360. Not only out of RPM but out of HP too.

Strangely, I have no issue with not doing the ton. My 750 does it easily, if I feel any urge to go fast. The 360 is a lot more fun 50-70 mph. Handles nice at that speed, it's in the power band. Prefer the fun over speed.

Downhill, with a tail wind, and a JATO pack assist, you might get it to break 100 mph. But don't count on it. The 360 was a more "eco-friendly commuter" platform than it was anything else. And it failed miserably at the ecologically friendly part of the design. Fantastic little town machines though.
