ugh. it really sucks that you have to deal with a guy who takes pills for his brain damage and cant figure out how to screw in a bolt. ignore him if you can. we do.
allen bolts are totally the way to go, especially for a peoples pipe. you can try the long nuts too but they are still a tight fit for a socket, and depending on your cylinder, it can also be tight for a plain old wrench. we install mlm pipes on every custom build we do at the shop, seeing as mlm is a block away. you can take my word for it, or the guy who called you an idiot.
keep at it, tomos are super easy to make go fast, but i think from here if you have a jetting question, a new thread may be best as this ones got shit all over it lol.
do it brother!
