Edelbrock 60069 heads.

427stang,
   Thanks, I'll leave them alone. Where they dump out into the engine they are wollowed out quite a bit. They're a lot bigger than the C1AE's. Jim

 I disassembled and assembled an Edelbrock headed 390 that had ARP head bolts. The nightmare was ARP used a reduced socket size then factory Ford. The problem was they did that with a 6-point head not a 12-point as is the custom when dealing with higher torque on a smaller bolt head. Man getting a weenie 6-point broken loose and later torqued up was scarry for it wanted to slip off and you could tell it did not like seeing that much force.

Qikbbstang,
     As I was pulling up the last head bolt on the 1st Edelbrock head that required 110 lbs torque. The torque wrench broke loose and I instantly thought I'd broke the ARP bolt or the threads came out of the head. I felt like throwing the torque wrench across the room or at least cussing out some idiot that thought 110 lbs was needed to torque down a head.  I put the torque wrench back on it and started pulling to see if the threads were gone. I estimate at about 80 lbs the torque wrench broke loose again. The socket had rounded off inside thank God. I torqued the other head to 100 lbs with a new socket and left them there. After I get about 30 minutes run time on the stand I'll retorque to 100 lbs. I don't want to go to 110 again. 100 lbs should torque a head down. Wouldn't ya think?

I've read that ARP recommends 75 ft-lbs or so with ARP lube which is different from Edelbrock.  I've been taking the head bolts to 85-90 ft-lbs with ARP lube.  Others have used the Edelbrock numbers with no problems.  If your block has been torque plate honed, I would use the torque that was used with the torque plates.
ARP seems to have come out with a new lube so I don't know what that does to the numbers.  LOL
I think you will be fine.

ARP's new lube is not as slippery as the old stuff, so the torque numbers with the new lube will be lower than they were with the old lube.

If not as slippery the tq would go up, more effort for the same clamping force.

I decided to retorque the top row of the 1st head to 100. That way they'll all be the same like the last one I put on. Shouldn't hurt anything. I hope.

You'll be fine

Get the old girl running already

(Who am I to talk, I did initial break in for the 445, but still no fenders or doors on the truck LOL)

Yep,  I think I had it backwards.  The new lube is more viscous than the old ARP lube, but maybe it is actually more slippery.  To get .006" stretch on a Crower rod bolt I needed 82 ft-lbs with the old lube, but only 75 with the new stuff.

Where can one get a burette for CCing???  Clifford

[jayb]

Summit Racing sells them, just do a search on "burette".

Thanks Jay.  Clifford

I just use a veterinarians syringe they come in huge sizes then there is little math involved.

[390 Cougar Conv]

Thats a good idea, never thought of that. Thanks Clifford
