I thought the point of a 12 point bolt was to be able to get more turns in a tight space, but if you can’t use an open ended wrench it’s totally useless. I’ll be switching to Allen heads next

Worked awesome! Have Vortec engine and these 12 bolts were all my exhaust needed. The head could be a bit smaller still as my Hedmann headers still get a little stingy on a few spots but overall I like them and know quality ARP will last.

Worked perfect for 98 k2500 with a 350/5.7

Great quality real ARP product, fits nicely. Heads are 12 point 3/8s so it makes it easier to get a boxed wrench end on them
