Re: 68 amx head gasket
ZX2guy,
The bolts on the Eldo were probably over-torqued the last time around. If they're stretched, they're stretched! Simple as that.
Felpro "Perma-Torque" (pn 8266PT-1) gaskets are the blue ones (the suffix "PT" is the clue). They use NO SEALER. EVER. We se this a lot. What fits and works well on older cars may or may not be similar to what works on modern cars. The laminated gasket discussed above is more for modern engines.
There was a yellow Gremlin running around Tuscon about 15 years ago, with a blown 401 in it. Talk about a BEAST! It could hold the front wheels through 1st and into 2nd. I heard it ran in the low 10s, but was never there to actually see it. I DID see it pull the front wheels in the IBM parking lot after a "hobby" show.
When we build hot rod Ramblers, we add an extra row of head bolts on the bottom. The gasket problem is well known. By drilling four well-placed holes and using 3/8" bolts, we rid ourselves of the problem. We also use Pontiac intake valves and some Chrysler trinkets inside.
Ramblers are pretty cool... Doing a 360 for an '87 Jeep J-10 right now!
