can i re-torque stock head bolts

Yes, there is an order and it is critical.

Here's the service manual's complete section on the head and related work: http://www.cygnusx1.net/Supra/Librar...ection=EM&P=32
Pay attention to all torque values.

The third image down shows the order for removing/loosening the bolts. Use the opposite order for tightening.

oh and is there any risk of the head bolts sheering off because theyre kinda old?

oh and thanx

I would be flat out amazed if that happened. Worst thing I've ever seen is people stripping the sockets out from not ensuring the driver was in all the way. The stock head bolts are VERY robust.

thank you so so much for your help. youve always helped me quite a bit.
and would you mind replying to my thread about removing the fenders front lip and bumper? if you search fender removal it should be right at the top

oh thanks again for all your help

If I had much to offer on the fender removal I'd gladly offer it up. I'll think it over and post back anything that I can think of which isn't obvious.

Would you mind please posting MKIII specific threads in the MKIII section? Some of the folks there may have worked on the fender more recently than I, for example and they may be more likely to see your post there.
Thanks.
