Default Where to find JDM B16A Torque Specs?

Looking for all the specs that have to do with headgasket swap. Last one I did i used the USDM specs from b16a2 and headgasket is leaking oil now. Any help and links would be appreciated.

Same Specs as USDM motor, the problem may have been the headgasket was put on upside down, or there was slight warpage/crack to the head, or the block deck face was not straight.

Did you clean the threads with a tap before installing the headbolts last time?

Did you torque the bolts in stages? what lube did you use on the headbolts? and what type were they (OEM/ARP?)

i shaved the head down and had it tested for cracks. so the heads strait.

I cleaned the threads off by whiping them down and used a light glaze of motor oil

I torqued the bolts in two stages to the specs off alldata. They were OEM bolts.

I purchased a new head gasket set and some ARP head studs.

Any ideas based on that info i gave you would be greatly appriciated. And any tip installed would be great.
The ARP headstuds came with their own lube and i looked up to do a 4 stage torque to 80lbs on the ARP head studs. This sound right?

alot of people sugge4st getting a tap into the threads that go down into the block that the bolts go into. they usually get crap in them that keeps the bolts form actually torquing down properly. you may just have one or 2 bolts not seated all the way...


do you have access to a digital camera? i would like a pic of where the block and head meet under the vtec solonoid. if the headgasket isnt on upside down or anything there should be a little silver tab with a serial # on it for the headgasket.
