Quick lash ajuster choice question.

[90gst_sean]

I bent ALL my valves. (except one!)

I have a spare head to run wile I build the broken head.

The broken head was in the machine shop 20,000 miles ago (clean & pretty).

The spare head has 130,000 mile on it.

I plan to purchase 3rd gen revised lash adjusters for the broken head build.

Is there any reason not to swap the 1st gen adjusters from the clean / broken head into my spare head to get me by?

I have adjusters in the spare head, but the broken heads adjusters are cleaner.

The broken head has 180,000 mile total, but again has seen a machine shop (20k ago).

I could also try cleaning the spare heads adjusters and run them.

As far as I know, both heads are 1990's; but there is a small difference between the two sets of lash adjusters. Its in the size / length of the groove on the adjusters sides. Where the oil entrance is. Its not the oil hole size, just the groove around the adjuster. I was originally under the assumption that the spare head was from a non turbo until I noticed that there was no turbo oil feed galley plug. It was open and unplugged, read for a turbo. This is good for me now that I need it.

I am swapping the cam's to be sure anyway.

Thanks

I'm not sure if you damaged the clean adjusters when you bent the valves, but you may have.

I'd pull and clean the adjusters from the spare head and re-use them in the spare head. I've read folks saying that you should reinstall them in the same place, but I don't know if that's important. But I wouldn't trust the clean head adjusters.

Then I'd do as you suggested and get revised Topline adjusters for the clean head when you rebuild it.

My $0.02.
