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.

easy to install no slip on wrench

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 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
