Don't do it! You need the gasket to create a seal between the head & cylinder.
(you would never run your car without a head gasket!)

i ran with no base gasket but i kept the head gasket. it will do the same thing, instead of a paper gasket you use permatex sealant,

If you remove the base gasket, it changes the port timing...
The correct way to increase compression, is to mill the head.

Some engines do better with the port timing changed due to the base gasket being eliminated.
Others hate it. The manufacturing tolerances are not held to much of a standard, so each engine has it's own little quirks. It's fun to play around with these little engines and experiment with them.

your right there my friend, and it really tests your abilities as a hobbyist engine tuner. One misstep that you think is great can gernade the engine in a matter of days while some other small thing (like me removing the BG) will make it work like a charm for hundreds of abusive miles.....

i forgot to mention the port timing. I lowered mine because at BDC the pistons top was actually lower than the bottom of the exhaust port i wanted to get it all out. I had a little more bhang in the engines torque all around. Good stock mod.

On the new engine Im not sure if i want to do very much to it aside from a basic "tune" i dont expect arm ripping powerbands to be gotten reliably lol

i've been having problems with the head gasket leaking, everytime i start the engine when its fully cooled id get a little puff of air coming out hitting me on the leg that goes away after the engine runs for a few seconds. today i noticed a corner of the head gasket was ripped off, so i took out the gasket and used some of the grey rtv gasket maker stuff to seal it up. gonna try it out tommorow, i really hope it works.
