4age 16v - low compression

[number_33]

Hi guys,

I have a 4age 16v bigport. Rebuild with high lift cams in and ex. I got the shim kit, HC piston, valve springs, and practically everything for the head.
*Added = Using a ITB BT*


As for the bottom end, using a rebalanced stock crank.
Engine has just done first initial stage of run in with rev limit on 3.5k

Problem:
The compression is evenly low on all 4 cyclinder. Sent to the engine builder, for check-ups and the head and bottom is fine. Can't figure out what is the problem and at the moment the mechanic and engine builder reckons its the crank pressure. They are telling me that it is not cranking enough of pressure to get the compression up with the high lift cams. Any ideas?

Basically, has anyone used before a high lift cams and have similiar problems? OR is there something i am missing that might be causing the problem?
