UPS are awful for importing stuff. I insist on fedex every time I get stuff from the states, never had a problem with them and import duty is paid on your behalf and then you’re invoiced after delivery

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.

I purchased the last set of turbo lifters from, conceptua_performance_tuning.

When I rebuilt mine a while ago few still tapped and OEM were NLA. New cams you need solid lifters and I did not want to spend that much.
