Dont reuse head bolts, they have a habbit of stretching when there reused. Get some ARPs.
If you must use them torque them down to 70lbs with some kind of moly lube.

Seriously dont. Either retorque them or get some ARPs.
Also make sure you torque them in a sequence (sp?)
9 5 1 3 7
8 4 2 6 10
Starting with 20lbs then 40lbs then your final torque.

Re: D16y8 Head torque specs!! ASAP!! (berettagtz117)
Well I havent driven it yet but I did start it up for a few seconds then turned it off to see if it would start. Is that going to affect it in any way

WEll since its all together you can tighten it to spec, tryit out and see how it goes.. If it doesnt work you will have to get new gasket. If you only started it and didnt drive it you should be fine, just tighten it down and see how it goes..

Re: D16y8 Head torque specs!! ASAP!!
Wow, I'm astounded at the variation on this! I just got a head resurfaced for my 2000 Civic EX (D16Y8) and went torque down my new gasket and new head bolts. My Chilton manual for 1996-2000 Civics states in the text to use a 2 step procedure: first to 22 ft-lbs, then to 61 ft-lbs, A table of torque specs later in the book says the same. But the diagram that goes along with the text says 72 ft-lbs! This discrepancy led me to look online, where most information I find gives a 3 or 4 step process that stops at 49 ft-lbs. That is quite a wide range: 49 to 72! This is about the only thread I can find anywhere that questions the 49 ft-lbs, but doesn't specify what it should be.
Is there some way to settle this? I normally would go with the book, not the internet, but when my book gives me two different answers, well WFT?
Thanks!

Re: D16y8 Head torque specs!! ASAP!!
The proper answer is to consult the factory Helm's manual... a Chilton manual is NOT the factory specs and there are errors in their discovery and printing. I can verify the spec for you on Tuesday when I stop by my Tuners shop if that helps... I am confident that it isn't 61 or 72 ft/lbs. The real answer is closer to 49 ft/lbs if you are using STOCK head bolts. Aftermarket head studs will have a higher torque value and this is where you may be getting confused from your online searching.
