PTV clearance on stock 94GT shortblock

[stangzroastrice]

I'm running a set of ported GT40's (non-p's) (never milled, nothing like that) with a Comp Cams xe270hr-14 camshaft (.512 lift intake/exhaust). Will I be alright to run Crane/Ford Cobra 1.7 rockers or you think that would be too much lift for the piston to valve clearance with the stock pistons?
thanks

yeah after a little research it seems as if i may run into PTV clearance issues, so i'll just stick with the stock rockers for now, easier on the wallet anyway.

you may still run into clearance issues with the 1.6's... my TFS 1 had barely enough clearance but on AFR 165's.
