dual pattern cams

I've had a rocker arm stud pull out as well on a set of 68 302 2v heads... my solution was to tape off everything around the hole where the stud was and I tapped out the hole for a screw in stud and was real careful cleaning up the mess of tap shavings. Worked great and never had to even pull off the head.

I'd still bet that the retainer hit the top of the valve guide... or coil bind.. You MIGHT want to check the cam for damage or rounded off lobes...

Well, while I was at the machine shop, the guy pulledd off all the springs and we checked each valve for ease of movement. They each were very, very sticky. I do have screw in studs and guide plates. Unfortuantely, they didn't keep my old valves for me to see. But they said the one that I thought was bent came right out. In my mind I can see the valve gunked up enough to not close all the way. I'm going to try and get it back together today. I'm going to spray some foamy lube on the top of the valve spring to try and get the gunk off the head of the valve, and see if it will run. Again, other than the one pushrod and broke roller, we can't find any evidence of impact any where. IF the valve didn't close all the way, not because it was bent, but because of gunk, it would also show lower compression. I know it sounds like BS, but I'm at a loss.
We'll see what happens when I fire it up tomorrow !!)

And, why don't my links work properly down here?????

Fresh heads shouldnt have been gunked up from bad gas though...

Try putting [url] in front then the same thing with a / in front of url after the link.

I know the heads shouldn't be gunky, but did you see those pictures?? If you cut and paste, the link works fine.....

PS, the machine shop only took off .006 from the head, just enough to true it up......

Another stupid question...

But your rocker arms wouldn't be railed would they? One of my friends about 10 years ago had a hard time getting his 289 to run after it was rebuilt...

After a couple minutes, I pulled off the valve cover to discover that there were railed rocker arms that were put on the engine. He was lucky that he didn't lose any retainers as the rails were pushing on the valve spring instead of the rocker pushing on the valve. A quick replacement, and the thing ran like a charm.
