Retarding by 1 degree isn't particularly an accurate way to do it, you need to confirm lift @ TDC with a dial gauge.
they run 1.25mm on the inlet and 1.05 on the exhaust, the trouble with running them retarded is that the torque will be lower and you'll need to rev it higher to find the peak, which as Anthony said puts you at the risk of lifter pump-up.
Catcams report 17 LBFT on top of the stock 145, given that some similarly cammed 2.2 XU engines haven't broken 200 lbft I highly doubt yours will even be at 170lbft with the retarded cams.
