    83405 is rated 3.7 out of 5 by 11.
    Rated 5 out of 5 by from Tear down and upgrade and upgrade some more A guy can buy the cheap torque to yield bolts or buy a set of these, I've personally used both and the cheap torque to yield are perfectly fine but if you like the ease of simply torquing rather than trying to watch a degree wheel these are much nicer, plus if you intend on a future tear down these are definitely the way to go.

    Rated 4 out of 5 by from these worked well for me I cleaned threads well with solvent and home made tap (old head bolt with v groove) that was very important prior to install. I had engine on stand so I could easily flip it over and flush with solvent. I also used arp high torque grease. I couldn't install threads by hand but they went in easy with a speed handle. I paid $85 and would buy again for that price. but I give it 4 star because its now listed at $135. I also believe that a couple of bolts were not straight by the way they threaded in but they all worked out.

    Rated 4 out of 5 by from Great bolts Decided to save some money and go with these over ARP bolts. They seemed like real good quality and no problems yet.

    Rated 3 out of 5 by from they work Bought these because ARPs are out of stock. Next time ill find ARP bolts. They did work but the threads arent the best on these. Id say about a third of them went in like they should.

    Just had 2 studs snap on speedmaster studs and looked at others that had all streached out of shape. I know they are made in china. Where are your bolts made and quality compared to speedmaster studs?

    Asked by: Hotrodphil
    These are made in the USA and are stronger than the Speedmaster bolts.
