intake bolts

is it just me or is it that the intake bolts suck, i broke my torx bit off in the bolt, how tight are those things? now I have to figure how to get the bolt out. Im not having any luck. does gm still sell those torx bolts or is it better just to use normal bolts.

I saw a company listed on eBay selling bolts for SBC motors. It was http://www.boltlocker.com I'm waiting on a response from them now about the intake bolts.

You can't use the allen head bolts for the actual intake, the heads are too high and the runners won't clear them when you go to put them on.

One of the reasons GM used the torqs bolts is that they have a very low profile head for clearance (they also used them to tick everyone off)

Hex heads are a tight fit too and won't work with the SLP runners.

they definently did it to **** me off. can I get replacemet bolts for the intake bolts that I screwed up? knowing chevy there 500 dollars a piece. i had to cut the head off the bolt to get the intake off, know I just have to get the bolt outta the head. Im having all so much fun with this.

They are pricy through GM...about 3.50 each for the longer ones.

Seems your problem isn't the bolt, but maybe a low-quality Torx bit. I had issues with breakage of bits and sprung for the 60 bucks for a good set, I use the "Asian-bit's" for trim and interior stuff.

you can use the hex head bolts. but you will need to lift the fuel rail up to get the runners off/on. my uncle used them on his 91 TPI motor into a 66 chevelle.
