cylinder head torque settings on Xflow

[kingofthetwisties]

Guys

I am just in the process of changing the old cylinder head on my 711m xflow for a stage 2 unleaded head from Burton Power.

Can anyone let me have the torque settings for the head bolts?

According to the Peter Wallage book its:

7NM

28 to 42 NM

70 to 76 NM

then after 10-20minutes 90-97NM

then after the engine has warmed up (15 minutes at 100rpm 90-97NM

I assume what he means is some value between 28 and 42, but obviously the same value on all bolts.

No idea if it is different for a stage 2 head, but that's the values for a 711M block.

If you need it in kp.m or lbf.ft let me know and I can post it.

Do you know the tightening order? If not I can scan in it and post.

That's all quoted from the book, not tried it myself yet, but will be doing soon. Let me know how you get on.

No worries, its all self-interest anyway, as I need to do thre same soon as well. So hopefully I can ask you questions too.

By the way, do you have the engine out and back in yet?

Yes, I hired an engine crane from HSS on friday. £35 for the weekend.

I got the engine out on friday eve. Cleaned it up and gave it a lick of paint on sat and got it back in today.

I am now just bolting averything back on.

Should get the head back on tomorrow now I have the torque settings.

The only thing i'm worried about now is how it will run. I stripped the carbs and cleaned them completly and have put them back together they look so much better but they may now need setting up properly.

I also need to replace the exhaust manifold bolts as they are all a bit worn.

All in all though it was not as difficult as I had imagined and I should have it back on the road next weekend.
