Have been looking for a set of caps that I've seen used on engines and carbs that are out of bike/car that plug up the exposed holes (instead of the rags you see stuffed into intake holes) to fit most things for a 1340 EVO and super E carb. I need sizes from cylinder bore size to intake holes to little pipes and holes where media could bet in during hydroblasting and other crap while the engines apart. The best pics I could find on google are these.

Any help would be greatly appreciated as I'm not even sure what you call them. I know there is a type out there that is tapered so that you can fit a wider range of int diameter hole. (Insert crude jokes here) many thanks folks! 

I would rather use rag or duct tape, not something that could fall in somewhere you don't want it to.

Just my 2 cents

Yeah I spoke to the hydro blaster and he said that tape and water will send shit down into everywhere.
That's why I'm after the plugs. I'll wedge them in and tape or glue in place. The tapered ones would be best option.
I was the same thinking at first till I learnt how small the glass beads are in hydroblasting and told that he's seen it before with tape n rags and it's a no no if ya wanna keep the inside clean and glass bead free.

yeah fair enough, I didn't read the hyro-blasting bit, my bad... it was early... not really up with hydro-blasting, never had to resort to that
