Here is a update so I got a new roller cam and lifters, had to change the valve springs to get a 235pound seat pressure. Replaced the springs. Went to install the new roller cam and it went all the way in except for the last cam bearing...so now I need to have the cam polished on the last...

In the attached picture it says make sure that the hose are pointed down and in towards the valves.. I definitely want to make sure it's right. Any thoughts is appreciated

Not at all. I would like to know how it goes when I put it back together and if the tops of those valves are okay in that one picture

I found this. But not sure

This is how I had them when it was first ran. I think they're correct. When he verification would be appreciate it. Thanks

That's my question. The first pick shows the rocker arm correspond into the valve in question The very top tip is smooth and square, but I have two of those that are beveled like that. For some reason the bevel is smooth as well by the looks of the rocker arms. I don't how it happened or what...

I noticed a couple of maybe issues on my valve stems. Not sure what to make of it. It could have been already like that from the machine shop. Not sure

Yes

I just talked to my cam guy again and he said to measure the pushrod length and add 15,000. Does it sound right

It's a punch in the gut feeling....lol so now that I am gonna try the roller hyd lifter route....do you know what my preload I believe it is that I need to add to my push rod measurement. I am running the stock rocker arm assemblies.

The cam guy said all I would have to do is add a 15 lb inner spring to make it 125 lb and that would be sufficient for roller lifters using the stock rocker arm assembly with the correct sized push rods.

110 17/8

I checked with my cam guy today. He said that my springs should be a 125 pounds and the ones I have now are 110. So he's going to sell me some inner springs that are 15 pounds. And get me a roller cam and lifters. That doesn't seem like very much. But he said to run the roller lifters it only...

This is my current cam specs for a supercharger I would think you would want a little different cam..

Sorry I misread. There was no hole in the lifter to start with. That's what I found when I pulled the lifter out a tiny pinhole. It wore down pretty good

There was a little hole in the bottom of the lifter

Yes

I just wonder why it was only one lifter. Oh well, I need to make a decision on my next course of action

It only has one spring. It has a enter retainer

That is the decision that I'm trying to make whether to try a new flat tap it cam and lifters again or go with a roller lifters and cam

So now I have to decide if I want to tear it down and go with roller lifters. Or get another cam and lifters and try again.....

Here's the latest pictures. The cam doesn't look. Wore out as bad as I've seen them before. I'm just wondering if it's okay by the looks of things to go ahead and switch? Cam over to roller lifters or does it need to come apart?

So the lifter come out with not much effort using a little tool. The cam itself looks pretty good. What's a chance of just the lifter being bad? I also check the oil and didn't see any shiny particles in it as the cam. Like I said, looked good. It's not rough or anything. I'm looking for a...

Just out of curiosity, what's involved in running hydraulic roller lifters using the same rocker arm assemblies

Chet hurbert....can't believe it would be that fragile lol

That's what I was thinking...

I pulled the valve cover off of the passenger side. I am able to pull the lifters up through where the push rods go in the head.on a big block. Without removing the intake. I've got three that are partial collapse collapse. And one that lost all of its prime. It's one of the three I can't get...

I took the car out today for a short drive after it really got warmed up. The idle oil pressure is back down to 15 to 20 but the cold pressure is increased. It seems to be working like it. Should the oil pump. Still have the lifter or rocker arm noise when it cools down. I will check the rocker...

With the stock oil pump I would run about 40 lb cold and about 15 to 20 lb when it was warmed up. So I took out the purple spring and put in a black spring. Now the pressure is about 60 cold and about 40 warmed up. The noise seems to be going away. I haven't had a chance to drive it yet. Cross...

So I went to the garage today and manually turned the engine over and brought the valves on the pasture side each set up to The closed position.. after going through the valves on that side, I have at least three lifters that are not pumped up that is I mean when the valve is closed I can push...
