CG 230 cylinder head - Page 2

I'm going to try the gasket thing Dan mentioned before I go all crazy on my head. Is the below J-B Weld 31314 Red Silicone Gasket Maker the right stuff to use for that?

And the below gasket from CSC?

Lay a strait end across the head and pick a point to take a measurement. Keep checking the measurement as you sand it down until you removed the amount you want. I have a wright up some where on here.

Honestly, I don't recommend it. The headgasket is going to be good for a small bump and a little extra power, but leave the base gasket alone. If you must do it, don't use red RTV. Use something like Hondabond HT or Permatex Ultra Grey https://www.amazon.com/Permatex-8219.../dp/B000HBGI8K

Is the red stuff too "permanent" or something? I was thinking about trying to replace both bottom and top gaskets with this stuff. I even saw some people on other posts claiming they don't use gaskets AT ALL!

Nope, don't use the red stuff, it's not designed to constrain that sort of pressure. Also, it tends to fragment and clog up oil passages/pumps. If you don't use gaskets, you'll either need perfectly (re)machined surfaces on a Chinese motor, or you'll leak oil. You definitely need a head gasket, too. You'll potentially need shorter pushrods to. Just listen to Dan.
