I need some help. Had a qestion regarding the amount of torque the head bolts will need? In the book I have it has 2 stages first torque all the bolts to 22ft pounds in sequence. Then it says large and medium bolts 80 degrees and smaller bolts to 67 degrees in sequence. I never torqued lt1 heads but I find it strange most heads I have done require 3 stages. I was wondering if this was correct. Also My digital Snap on torque wrench Will only read a minimum of 25ft pounds.....3 pounds more then asked for anyone think it will be a problem doing 25 foot pounds the first pass???

 

When it comes to torquing heads, it's very crucial that it is done according to spec, down to the last torque value. I won't say anything else.

But I think you have the strangest signature I've ever seen...

 

First, put in all the bolts finger tight. Then torque down to 22ft/lbs from a inside to out circular pattern if you do not have a manual with the torque pattern, but will be ok if you torque them to 25ft/lbs. Then in the same pattern torque them to manufacture spec.

 

The specs they are giving are for torque to angle. The first step uses a low torque setting because there is much smaller error involved at low torque settings. However, torque to angle is very accurate as it isn't friction dependent.

Please go to advanced tech and read the thread on torquing cylinder heads. It's long but you may get something out of that discussion. You do need to go through the bolt-thread conditioning process. But that's outlined in the advanced tech thread.

Post here if you have any questions.

I guess I have the correct torque specs. I just hoped I wouldn't have to buy another torque wrench and just use this over priced one by snap on. Ill be giving sears a visit tomorrow in hope to find a smaller reading torque wrench.

 

If you had read the info I refered to, you would have found your answer. Would save you money on a torque wrench you don't need too.

Good luck.
