What's that header feeding and how much power you makin ?
 
Fuck! One drawback to the prybar, cant easily hold the spring down and use both hands. See if you can move the spring and retainer away from the lock, if that makes any sense. It should have some wiggle room with one lock out.

Sometimes have to slightly move the spring and retainer around to get them back in also,
 
The retainer and spring aren't moving at the moment. I'm tapping on them with handle of the dead blow and no luck. I can't believe this shit.

I tried to take the exhaust valve spring off. They were locked to the stem so I hit with hammer as suggested just to loosen it up One went flying, the other lodged itself just like the first one.

Unreal. Honestly fucking unreal
 
I've never had a spring compressor I liked, other than seeing the big buck boys use the billet aluminum air powered ones.

Tap, not "hit"
And I wouldn't be tapping on the lodged one now. Do what boosted bullet said. Some downward and side pressure at the same time away from the binded side
 
I took it to the machine shop and I'm glad I did. The locks are fucked up and deformed. He used the nice air tool to get them out and threw in some new retainers. 20250625_150526.jpg
 
I want to point out something stupid that has eluded me. I've been stressing about the lifters being Hydraulic and trying to find a solid roller lifter the same size or cup height or whatever it's called. The size doesn't matter at all. The lift is the lift, regardless of what you have in the lifter hole or what pushrod you have in there. Adjustable pushrod might make it easier depending on your setup as long as you have lightweight check springs.

I saw Richard Holdener put a flanged nut upside down in a hyd lifter to make it a "solid" and it made the light bulb go off. I've seen you guys say stack washers or weld it or whatever but my mind was convinced it had to be the right size for some reason.
 
Used an oil can to pump oil into the lifters. Checked ptv again with gasket on there.

.215" intake
.235" exhaust
.100" radial

Yeah I agree. At around 600 lbs open the moroso gets a little tough. And if keepers are stuck.

The Moroso has always been fine for me. If the valves have been floated the locks are usually pretty stuck. I just whack the retainer with a plastic hammer and then they will be fine. I have never run more than 300 pounds on the seat so the Moroso tool works fine.

Without a head gasket on there..

I have .240 intake valve clearance and .302 exhaust valve clearance.

Maybe mahle takes a wild ass guess as to how much valve relief to put into their pistons

Sounds like you didn't need reliefs, lol.
Longer duration and tight lsa gets yer valves nice and close to the piston 😆
