are headbolts interchangable?

[Znut73]

got a new block(F54) my question is can i use L24headbolts on the 82L28 or do i need to purchace difrent ones for that year and are the torking specs diferent if so does anybody know them. Thanks

The bolts are all the same in the L series and the torque specs are the same for all non-turbo engines. The Turbos' had a different head bolt which could be torqued about 10% more than stock, and you can use these in any of the L series engines as well. They are about 60 bucks for a set if you wanted them.

Thanks 2many anothe question do you have to buy new ones or can you clean the old ones with a die and install

[2ManyZs]

Clean them with a wire brush by hand, or on a drill or bench grinder, whichever you have. When you are ready to install them, put a little engine oil on the threads before you put them in the block to keep the bolts from seizing, but the biggest advantage you will get is a more accurate torque setting with them if they are lubricated.

2ManyZs - Shouldn't a high tempature antiseize be used?

I would think that a little oil would burn in there, and if removed again later, would make them all look like the ones that come out next to an exhaust port.......no??

You can use high-heat anti-sieze..

But, there are engine builders who will swear that anti-sieze will do the same thing and others that will tell you that the anti-sieze is not good when used on an engine where you have steel, cast iron, aluminum in contact with one another as well...

The best thing I can say is use a little anti-sieze on the threads only, and use a little oil under the head of the bolt for lubrication when it comes in contact with the head, so you get a true torque reading. I'd prefer not having any anti-sieze not getting into the oil if at all possible.

Guess it all boils down to personal preferrence.
