Are all intake bolts the same??

Are all of them 3/8" x 1 1/2 " ??? It seems that all 4 outside bolts need to be shorter than that

They all should be only 1" long.

HMMM I was told by other board members in a previous post that they are 1 1/2". Now I am second guessing myself. Does anyone know for sure???

Never bud. I just wanna make sure. But if you are sure, I will use 1" bolts.

I just went to the shop, and measured vintage intake bolts...1 1/8 inch long. So 1 1/2 would bottom out in head. Use the one inch.

All the bolts on my intake except the outside ones go straight thru the head into the lifter valley. Does it depend on the heads? Anyway thats why I put sealer on all the inside bolt threads. And I use 1 1/2" bolts on those inside eight. Some Fel-pro intake gaskets are too thick for just 1". IMHO.
