Default LQ4 PTV clearance with 59cc heads

I am wondering how big of a cam I can run in this LQ4 with 59cc heads. I wasn't sure how much of an issue I would have since I would be right at 11:1 compression with this setup. The heads are a custom ported 241 set that is milled down to 59cc and cometic .040 gaskets. I am used to my old LS2 with 11:1 and I am fairly knowledgeable on what cams fit that motor. I just dont know how much of a difference in clearance I will have with the LQ4. Any input is appreciated.
