I was looking at these, never heard of the brand tho...what do you guys use? How much does OEM cost?

Why not just use stock bolts? I wouldn't buy anything else unless it was studs.

Unless there's actually something wrong with your original bolts, you can re-use them without issues. They're not torque-to-yield bolts.

Well Haynes calls for 168 ft. lbs. then an additional 90* then another 90* in their torque sequence......thats pretty friggin tight for such a long bolt. The bolts have already been through two torque sequences (once at the factory, then once by the PO) I just wanted to cover all my bases when i do the heads cause I plan on being pretty brutal on this engine and I dont want to pull it back out until I'm ready or forced to do the bottom end.

Everyone reuses them. You'll be fine.

You should read through that torque sequence again, a little slower this time. If you tightened it that much you would tear the block in half!

ok, gotcha, inch lbs......glad u called me on that. That bein said, the PO did torque it to 168 ft lbs then additinal 180*, he was bitching to me about it was all he could do with a cheater pipe to get it torqued lol...I'll probably get new bolts just for that reason. /thinks to self/ gotta quit skim-reading the service manual....

[SLODRIVE]

Yikes. If the PO really tightened the head bolts that much, no wonder you're having a problem now. There's a very real possibility that the block/head mating surfaces distorted from that much over-tightening, you might wanna get that checked out! You should probably chase the threads in the block too (if there's any threads left!).

Yea he said one of the bolts didn't feel like it really pulled down like the rest.

[kimokalihi]

That's pretty crazy. I thought that seemed a bit high. I never had my heads off so I didn't have to torque them down but I remember on my 89 toyota 4x4 the head bolts were torqued to about 80 ft-lbs.

I'm surprised you got those off and that he didn't strip threads. Luckily the threads are pretty deep.

[MTFB]

Havent torn it apart yet..lol

I partially stripped a block because I confused 90 degrees with 180 degrees, twice...
