What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.

Are these valve springs compatible with aftermarket camshafts?

What is the recommended installed height for these valve springs?
The recommended installed height for the Performance Springs for the 4G15 should be checked against the manufacturer's specifications. Generally, an installed height of around 1.5 inches is common, but precise measurements should be taken during assembly.
