Working on the new build heads today,
I removed the old springs and lifters then fitted the JWT springs and lifters then I planned to put the new cams in too but discovered all the lifters are spongy.
After dipping them in oil and compressing the pistons on them a few times all the air quickly came out,
However many of them, likely 10 are still spongy so not sure what to do at this point.

As a follow up to my jasma code thread, what exhaust is this?
As mentioned before it has sr 051 622 on the plaque.
