Full Length Drilled Dowel Pins

Ok guys I am looking to build up my 20b and I am looking to have a local shop do some dowel pinning for me. I do not want to use studs as I do not want any potential for coolant leaks from studs and nut locations over time. I am not planning on removing the motor for a long time and I am just looking for reliability. Or at least as much as you can get form a 20b.

As such I will be using additional OEM taper pins in the front housing to maintain the factory float for bore alignment.
But in the rear I would like to use full length drilled dowel pins. However I have not seen many options around. In reality I have only seen them from pineapple racing....

Are there any other full length drilled dowel pin options out there anymore?

Or has Studding completely taken over these days?

Note: I used a picture from a rotorooter93fd post. Hope you don't mind......
