80cc slant head mods?

[LS614]

Hi all
I just ordered the 80cc slant head for $13 from zoombicycles to bolt onto my stinger. Someone was saying that you need to modify the engine. Please tell me what this will involve, or direct me to a post that already has this info.
Thanks!

No need to mod the engine, but make sure that head is flat. I know, OK, slight chance that it isn't.

Why do the head come uneven sometimes? I'm also going to get one

Cheap China stuff. There I said it. He's selling them for $13US. How much do you be thinking he be paying?

Gotcha. Yea it is cheap stuff but it's still awesome. I may get the bolt kit that comes with all of the stronger nuts and bolts.

I have the same head. Arrived hugely unflat, lapped it flat (took some time) - it now slowly warps.....just not enough mass.
