Car Quest auto parts used to list them, but I have had no luck in finding them personally. I would check any "older" auto parts distributor in your area. They might have some sitting on the shelf and not reflected on the computer.

 

Also, keep an eye on ebay. I got five sets of fifteen thousands with some head gaskets early in the spring.

 

Good luck.

 

By the way, I thought you were going to use the the cam adjustment, chain guide from something else and a shortened link. Why the change to the shims?

well i decided to search through the archives on this site and it had been done. The engine only lasts avbout 10,000 miles before the guide gets all wrecked and flakes of crap goes into the oil sump. If i can find the shims some place else then i will do the p79. If i cant then im going to stick my n47 on there.

When I was having my head prepped at the machinist about 2 years ago he was looking for these for me and said either Crane or ISKY had them. Sorry can't remember which one it was.

 

Also, checked recently at the local machine shop and found them here too, on the shelf as a matter of fact.

 

I don't think they're hard to come by.

 

EDIT--Also, if you need thicker just stack them.

Use caution if more than 2 sets of shims are used.

Theres not alot of treads for the cam tower bolts, and I think the tourque is only like 12 foot pounds.

I installed heli-coils in all cam tower bolt holes due to pulling the threads out.

And of course, this was after the valve train was assembled. :bonk:

Doug,

 

The thread issue is a good one. Helicoils will strengthen the attachment. As to the number of shims. I don't see that two shims at .040 each (total .080) is going to be less of a problem than 5 at .015 (total .075), the correction is near the same, as is the number of threads of the bolts not engaged in the heads.

 

The requirement of this modification is to make up the amount cut on the face of the head at the came towers with the shims and the cut for a 10.0:1 compression is .080. If there is a reason not to stack, please let me know, as I am close to doing just that.

 

Thanks,
