Hydraulic lifters and how to test 'em better?

[rabbitman]

Good so far!!! I haven't drove it lots but it cranked less today than it did before.

I rebuilt the head myself, the whole problem was due to the valve stems protruding too close to the cam which I did know about the spec but for some reason I over looked it.

I totally enjoy driving this thing, cruises nice and quiet (compared to rabbit), has less power but I don't have the timing dialed in yet.

I'll keep you all posted on it.....

You say you rebuilt the head, did you also grind down the valve seats? Because that's the only way that the valve stems would be too long. A machine shop should check for this if they did the seats.

I did grind the seats and I did know about this measurement but I think I got interrupted in the middle of shortening them and skipped quite a few. Lesson learned the hard way, I wish I could blame a machine shop but I WAS the shop so I can't get my money back.

I have to mess with static timing and then timing advance and it'll be runnin' good. It likes to shudder a bit at low rpm/low power, when I pour on the coal it does fine until higher rpm then it sounds a little to marbly.
