Engine CLeaning Brush Kit
There are a lot of options out there, but this is what I found. Input is definitely welcome
This kit covers all of the sizes I measured on my block, with the exception of a 1" and 4". I can just use something else on the bores anyway...
Block Thread Chasers
I also bought 4 ARP thread chasers. Bought from Lightning Motorsports in LA (the state). They had them in stock with free shipping, and low prices.
912-0012 M6 x 1.0
912-0001 M8 x 1.25
912-0002 M10 x 1.25
912-0004 M11 x 1.25
Oh, almost forgot. Oil Galley plugs are M18 1.50 Found that here on NASIOC. Have not found a chaser for them yet, but I think there may be a sparg plug hole chaser that will work.
