273 adjustable rockers need refurbish.

And we're sure this is a case where the lifters haven't been pumped up yet or something? I'm certainly not telling you to slap it all together and hope for the best! That's just something I did on a cheap $50 Craigslist motor. LOL I remember you saying something about the Machine Shop being in business for a long time? And you're contemplating taking them back for a second time? I wonder if this is how they been business so long ? LOL what I can't get over is how you have a brand new cam with a stock base Circle brand new lifters that should all be the same brand new pushrods that should all be stock length and you can lay a ruler across the tops of your valve stems ? I'm just not seeing a reason for there being 3 or 4 different Rod lenths ?


="MOA, post: 1971739863, member: 45258"]What I found that I didn't like: three were at zero preload, the retainer wouldn't last long. One was .080 preload. .020 too much. With the valve moving up in the head over time that only gets worse.

With the new pistons, I don't want to rotate it any more than I have to without oil pressure/lube. Having to check and recheck the pre load has me rotating the engine more than I would like.

If I go with non adjustable and they're all over the place again,I guess I'll just take the heads off again and take them back to the shop that rebuilt them, make them get it right.

Getting different length pushrods for every valve is ridiculous.

I can't just slap them on there and hope they're right.[/QUOTE]
