@unijabnx2000 I thought he said they're ARP sold by Mazworx? In post #5 that's clearly what he says. I'm just speaking from the info provided bro. If the info Sean has provided is incorrect, well then my info will then be useless.

But then again, post #7 he says they're Mazworx studs.

Maybe @seanhaley79 wants to figure out just exactly what parts he has so he doesn't receive conflicting info from us?

The studs are manufactured by ARP. Mazworx has them made a little bit longer than the ones sold directly by arp so that they bottom out in the block. So its an arp stud made to mazworx specs.

I never even thought about that... I'll see if I can find out. The block was done 5+ years ago when it belonged to a friend of mine at that point. I'll see if he remembers.

Dont call them ARP studs. (whoever makes them for Mazworx is irrelavant)
The material, size, and installation is all different.

Fair enough, my apologizes for the confusion.

Just trying to help. @unijabnx2000 is someone who I've always looked to for providing great factual info, for whatever that's worth ;-) not to say mine isn't factual, just it's not useful in this particular scenario now having better information.

Don't give up Sean!!! I just solved a FIVE YEAR idle issue! NEVER give up :-) you'll figure it out.

Very valid thought...although I would think the compression numbers would be the opposite in comparison to the cylinders if this were the case, no? Highest compression numbers are on the end where the oil pump is.

you guys are getting too torn up over the head studs/head gasket, there's something else going on. Are you sure something isn't heating up and exposing a crack in the head or block? Are your ring end gaps in different positions? Just throwing ideas out there.

From my further forum searching, seems MANY ol Skool "gurus" suggest torquing in stages to 80ft lbs. 20, 40, 60, 80, loosen completely....re-do in stages.


If the tensioning of the head has been done using the 'mazworx' specifications, then this head has only ever been torqued to 60 ft/lbs, which is clearly NOT what is required.
An important piece of information is on the 'mazworx' specification sheet, which is: "Torque in factory sequence the following torque ratios". To me that means USE the factory sequence for torquing down the head, but substituting in the numbers that 'mazworx' provides, that is"
1st sequence = 45 ft/lbs
2nd sequence = 65 ft/lbs

Now, following the factory sequence the torquing is:
Factory 1st sequence = 29 ft/lbs
Mazworx 1st sequence = 45 ft/lbs

Factory 2nd sequence = 58 ft/lbs
Mazworx 2nd sequence = 65 ft/lbs

Factory 3rd sequence = 0 ft/lbs (all released)

Factory 4th sequence = 23-33 ft/lbs
Mazworx (use 1st sequence) = 45 ft/lbs

Factory 5th sequence = 90 +10 -0 degrees

Factory 6th sequence = 90 +10 -0 degrees

You have now followed the mazworx instructions ""Torque in factory sequence the following torque ratios" using their specified torque sequence ratios. The factory sequence is taken from the link posted above.

I think I have this right, but just to be sure, check with Mazworx if it is correct.

You are way over thinking it bro.

OP needs to do the compression and leak down tests again. Check/listen for bubbles in the coolant while testing. Report back.
