    ARP head stud part numbers

    I did a search and came up with two numbers

    143-4003

    143-4303

    Both are listed for a GM V-6 at Summit

    Which ones are the ones to use on my 91?

    thanks

    You need the 2.8 V6 Chevy studs,

    233-4003 are 6 point nuts

    233-4303 are 12 point nuts

    The 6 point version is almost $30 cheaper, about $85.

    yeah I saw that one was less money, as long as they both work then the six points will be the ones

    thanks

    Don't forget to order some ARP Assembly Lube, and ARP Teflon Thread Sealer also as they are not included with the stud kit.
