RE: HEad bolts
7/16 for stock heads but most aftermarket are 1/2" then you get the ARP biolts with washers

RE: HEad bolts
Head bolt holes are 1/2" on most aftermarket heads.
The threads are 7/16".
I have had no issues not using the washers.
ARP-3601 are some good cheap head bolts that are reuseable.
