Hi. I’m building a 8ba , and need new oil gallery plugs. I live in Norway and don’t have many shops to by inch treads bolts and flathead parts at all. Any one knows where to by I’ll be glad.
Regarding Stian
 
The stock plug has a screw driver slot but one can be made by using an allen pipe plug, making sure to remove material from it to prevent it from hitting the timing gear

Availability in Norway is the problem. Our inch based hardware isn't so common there. Having said that, a 3/8-19 BSP tapered plug may fit if the threads in the block are chased with the proper tap. Yes, some thread damage will result, but I'll bet it would be fine.

Norway does have access to EBAY as well as other suppliers.
Might not be available at the corner hardware store but a search online will yield results.

You sure you really want to risk deforming the original threads, IF it doesn't seal properly? Thread SHAPES and ANGLES are different, at the least. DD

The amount of leakage from the different thread pitches will be insignificant.
It is standard practice to drill a .040 (1mm) hole in the plug on high performance engines.
(to oil the gear)

Try hardware and plumbing supply outlets as well as EBAY as stated.
By all means do NOT do any odd size re-tapping.
The plugs are available.
