Supercharged H22a
are you using arp headbolts or new oem bolts? i used the molylube with the arp headbolts and went to 90 ft lbs after starting with 30 the going to 60 then 90... as far as oem goes
u do it in three stages but this is what autodata says:
30 ft lbs
50 ft lbs
75ft lbs last go round
if youre using the oem bolts over again, you might break them so id recommend against that.

What does this have to do with a S/C H22A? Has to be another Canadian question...
j/k 
Using clean 5w30 engine oil to lubricate the bolt threads and under the bolt head. H22A OEM tq numbers are as follows;
Step 1 - 29 lb-ft
Step 2 - 51 lb-ft
Step 3 - 72 lb-ft
P.S. I've never had any second use OEM bolts break on me yet. :knocks-on-wood:
Note: If they are lubricated and make any sort of noise while tq'n them down. Loosen the bolt, re-lubricate and start back at step 1. Noise = binding = improper tq wrench readings.
