Why buy 1.7 rockers, only to limit yourself on cam selection? And yes, you do torque the heads when checking PTV clearance...and put a head gasket in there as well. When you're talking .039-.044 thickness for a HG, plus the torque, it can make/break a setup working.
My advice...buy a set of used heads/rockers/pushrods from someone upgrading their combo. You get matched parts for cheap...that's what I did with my first build.

I have already purchased my cam which is a TFS 1 (.499/.510 lift with 1.6s) I have been extremely curious how compatible the cam would be with different types of heads and whether or not I can get more of a lift out of them. But I couldn't pass up an EXTREMELY low milage tfs1 for the price that I got it for.
John, what would be the best route for me to go if I want to try to fit 1.7s? I heard an edelbrock 2.02 intake would hit for sure, but 1.90s wouldn't? Not too familiar with cylinder heads so any knowledge would be greatly appreciated. Thanks.

The cam is a street/strip cam designed to make power below 6000rpm. It's impressive to make that power without having to rev the piss out of the motor. It matches perfectly for my road racing application, once you start going above 6500rpm for extended periods on a stock block you will be replacing stock blocks frequently.
