I heard the 3sgte valves work in the 5sfte build but I was hoping for something a little more performance wise. Anyone have experience with this? Wanting at least 350 hp.

9.5:1 is the static compression ratio of the pistons. Valves aren't measure in ratios, they're measured in diameters (inches or mm) and are the doors to the combustion chamber. The bigger the doors, the more air that can come in/go out, restricted by the intake tract and camshafts.
The other numbers are what is called "lift and duration" of the camshafts. Lift is measured in millimeters or fractions of an inch(it's easier to see a difference in millimeters so I rather go by that) and duration is measured in degrees (like the rest of the engine timing) It basically dictates how "wide" the door will open and for how long to allow the entry of air. There's a ton of different options to choose from but the most common to use are the webcams 294, 763 and 101 grinds. If you're going with custom everything, I would go with the most aggressive 101 profile. -------------------- 1993 Celica GT Coupe - sold
