4.1 head studs

[007gn]

hello everyone my question is what are the correct head studs for the 4.1 Buick block 291 casting- & using champion gn1 aluminum heads . The studs that were sold to me are wrong they're too long & I believe they're for a 3.8 . ARP#223-4204 & I'm wondering if these ARP#223-4203 are the correct head studs for my 4.1 gn1 application ??? Thanks in advance for all your help guys .

I had the same problem. I used the 223-4204 and 123-4201 and mixed them to get the correct length. I used the longer center studs with 2 washers. The problem is, Champion recommends the 223-4204, but that is for a 109 block with a deeper bolt recess.

Thanks for that info & I'm gonna look into this. I wanna be back driving my car.
