trickflow stage 1 and 1.7s will give valve float I have that set up gt40s with 1.94s 1.7s and trickflow stage 1 it produces too much lift and im kicking my self in the ass for getting it it feels slower than stock. the lift the cam and rockers is like .542 and I would just stay with a 1.6 rocker arm

If your experiencing valve float, why not upgrade to some stiffer valve springs? Those should keep them from staying open

OP, Im running GT40P heads btw, similar to yours, with stock valves.

I have stock port gt40s just all new hardware, I ran 1.72rr with fcam. Never felt any valve float or anything close to valve float. I'd recheck or redue your valve springs bro
