Valve Placement

what is this ssm site?

Your kidding right, streetsource.com

not kidding lol......i spend most of my time on sites not based in north america.

i hear lots of people saying negative things about the site,but i'll still check it out

all 8 of mine are in a bundle under the bed right behind the driverside cab. it's right near the muffler as well, about 1ft from it. It's been great for the winter because I just start the truck up and let it sit there for a minute or two and let the exhaust cloud up under the truck and it unfreezes my valves
