I'm getting closer to assembling the new heads on my 327 Chevy, but can't seem to locate torque specs for what I have. They're Trick Flow aluminum heads with hex head ARP bolts and washers. Got the bolts with the heads, but no instructions or specs.
Went to ARP's site and had no luck. Looked at kit numbers for what I have and they say the instructions aren't loaded on their site. Clicked on the "tech assistance" link and it says the link doesn't work. Really a poor web site IMHO.
From what I've gathered on stock SBC aluminum heads they are 65 ft. lbs. on medium and long bolts, but 60 ft. lbs. on the short. I'll go with that if I can't find ARP sepcs, but I'd like to be sure when I do it.
Anyone got any input, it would be appreciated!

This link is if you bought a bolt kit. Their site does suck! There is a lot of information but it put in an unusable format. I googled arp torque specs and there are tons of results. I'd say they are in need of a revamp.

I have had great luck torquing any SBC aluminum heads @ 65 lbs on all bolts using ARP bolts. I do this with ARP sealer on the threads and 30 weight oil on the washers and under the bolt heads. I also do this in four steps starting @ 15lbs. then 30, 50 then finally @ 65. After they sit for a day or so I re-check them @ 65. Also make sure the threads in the block clean and chased with a thread chaser not a tap. Hope this helps! Brian

Yes, that's the site I went to, and it's useless even if you have the part number for their kit. Most say it's not on the search yet, while others are only connecting rods listed. I went through every kit number listed that was hex head and non SS. Worthless site.

Thanks Brian! I'll do them all that way. The guy who sold me the heads and ARP bolts gave me the thread sealer too, so I should be set now!
