RE: Lean/Rich 302
did u follow the proper head tightening sequence? did u lightly oil the bolt so u could get accurate totque readings and did u follow the step procedure on the torque sa y if its 75ft lbs u do 25 on all of them 50 then 75?

RE: Lean/Rich 302
I have a shop manual that shows a diagram to tighten from the inside bolts out. It also says follow a "3 step" tighteing procedure so they wont need retorqueing" The 3 steps included 3 diff torque ratings. I followed both of these steps. I dont see what i did wrong besides low on coolant causing it to overheat. Can i just tighten the head bolts like 25 ft lbs over the max and seal it that way? -Jon

You run the risk of twisting off a bolt if you tighten it any more. There is a chance that you put the gasket on upside down. If I were you, I would just take the head back off and put a new gasket on, making sure the gasket is on right, and that the torque sequence is followed with a ratchet torque wrench.

Yes i did and even read the instructions on how "not" to tighted the outside bolts to much because it said they overhang the block<--- instructions said they not to tighten as much( they gave tq spec) so i followed that. The way its running is just so weak on the drivers side 4 cyls and u can feel it! I really dont think i did anything wrong! i know i may be getting pissy, this was my first rebuild so i read everything triple times although since its my first, theres even more room for error! thanks for helping. And i am going to try over tighteing the headbolts, in sequence by a small amount. ill take the chance oftearing one of the ARP bolts off or stripping it, if it does bust, ill pull it and figure something out then. Should i retorque them down while the engine isHOT or cold? -Jon

if it blown its blown torquing them more isnt gonna stop a leak id get a cylinder leak down tool to eliminate the head gaskets b4 i disassemble anything do that see which one its is then if theres a problem pull the head
