    JEGS Premium head bolts are available with a reduced hex size (1/2" compared to stock 5/8") with a wide area head flange that eliminates valve train removal to aid in re-torquing of the cylinder heads. All High Performance Series bolts are 170,000 psi chromemoly alloy steel, which is approximately 15% stronger than Grade 8. Each bolt is then finished with the distinctive JEGS J-Crown. Kits come complete with hardened double disc ground and chamfered 4130 heat-treated steel washers (also available separately). Head bolts and washers are coated with black oxide for durability. Bolts sold in complete engine sets. .

    83410 - JEGS Head Bolt Kits is rated 3.5 out of 5 by 2.

    Rated 2 out of 5 by from Nice headbolts but... Secured my bbc heads and went to install my Hooker super comp headers and could not install header bolts because header flanges touched the tops of the lower head bolts. Solution would be to grind the bottom of the flanges or remove washers from the head bolts. I did neither and went and put my stock bbc lower head bolts back on to gain my clearance back.
