i had the head gasket blowing problem i posted earlier this month on the 16th, my question now is if my head and block have been shaved off too much. how can i find out if it's gone over the maximum specs. do any of you folks have spec's on how much space there should be between the piston and the inside surface of the head.
i am think this is the problem because i've checked for dirt, rust and water in the bolt hole but it is clean in the inside.
the problem i have is, this is fallowing the haynes manual to torque, i start the car, runs fine, let it worm-up, as soon as i drive it or if it sits there long enough (15 minutes) it blows the gasket. the gasket blows through from cylinder 2 to 3 or vise versa in the prosses the main oil line that goes to the head and also the two main water hole in the center of the gasket blow through. this is going to be my fourth time putting a new gasket in.
i was also wondering if i could put two gaskets on top of each other for more clearance, if the problem is too high of compression.

1. Are you POSITIVE that the head and block are FLAT within the factory specs?
2. Your head bolts might be bottoming out in the holes before they are able to provide the required clamp load. If your head has been shaved too far this could happen. Remove 1/32" from the end of each bolt.
3. I doubt your compression is too high simply because I don't hear any comments about serious knocking.

Besides the ideas already shared, I had a repeating head gasket problem which turned out to be caused by a poor milling job on head and block. I hired a lousy machine shop and the left grooves every 1/8" or so which were deep enough to catch your fingernail. I finally noticed carbon traces in the grooves. After reworking the surfaces at a new shop, the problem went away.

I'm no Andy Granatelli, but it sounds like your problem is definitely related to how tight the head is clamped. Sure the threads are OK? Make sure the head and block are as perfectly flat as possible. You'd be surprised at how many slackluster machine shops are out there. Next, if available, I'd try shorter NEW studs, as the old ones may have stretched, and if so, they may be stretching every time you reuse them. After all this, there are always high performance head gaskets available. Good luck!

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->If your pistons are contacting the head, you will see smoothly polished, carbon-free areas on the head and corresponding areas on the piston. I think this is unlikely to be the cause.
Besides the ideas already shared, I had a repeating head gasket problem which turned out to be caused by a poor milling job on head and block. I hired a lousy machine shop and the left grooves every 1/8" or so which were deep enough to catch your fingernail. I finally noticed carbon traces in the grooves. After reworking the surfaces at a new shop, the problem went away.

I'm no Andy Granatelli, but it sounds like your problem is definitely related to how tight the head is clamped. Sure the threads are OK? Make sure the head and block are as perfectly flat as possible. You'd be surprised at how many slackluster machine shops are out there. Next, if available, I'd try shorter NEW studs, as the old ones may have stretched, and if so, they may be stretching every time you reuse them. After all this, there are always high performance head gaskets available. Good luck!
