VVT cam swap with no AFM... Tips?

[cam-]

I'm installing a Patrick G custom grind in a VVT 6.2L with no AFM and was searching all around for info and thought you guys might have some input? My plans at this point are to install the cam with the comp phaser limiter and fire it up. Try and get the idle sorted them tune the sucker.

I am worried about valve spring pressure as i am a dual spring fan typically but considering the VVT phaser has to work against the valve spring pressure I am probably going to get a single beehive. Likely the PAC 1518

I was planning on leaving all the VVT phasing tables stock for the time being I cant see how this is a bad place to start so if I'm going over the cliff here pls advise.

Cam specs are .600 lift 222/230 114+2

I'm hoping those with VVT experience who may have some helpful insight here will chime in. Thanks
