    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. .

    83400 is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from good quality I bought these bolts as an up grade and they work fine.

    Is this kit comparable to ARP 134-3601? I ordered them for a set of Promaxx SBC heads and didn’t notice until later that they specifically recommend ARP 134-3601

    Asked by: MGillam
    Yes, this head bolt kit should work for your Promaxx cylinder heads.
