Id appreciate if someone can help me out here.. Ive searched high and low here and havent found what im looking for.

How long are OEM b16 and b18c headbolts?

Ive got about 30 stock headbolts, and im just trying to figure out what goes to what. Ive got 22 7" bolts, and I havent measured the others. Just looking though, 2 are about 6 1/2" and then 6 are a little shorter than that.

Thanks.

the headbolts should have letters on the top. also, if you are just talking about b-series, the shortest would be the b16, then ls..(excluding the middle two), then gsr being the longest.

i may be wrong, but the top of the b16 should be blank, the LS would be represented by "r" and the gs-r by a "v".

hopefully that will help you.
