You don't sacrifice quality for a low price - get both with a Flo-Tek aluminum cylinder head. This Chevy aluminum head is loaded with high end features like bronze valve guides, multi angle valve job, and 3/8" screw-in rocker studs with guideplates.

These fully assembled heads have single valve springs (with flat wire inner damper) with a seat pressure of 130 lbs. They are compatible with solid (mechanical) flat tappet or hydraulic flat tappet cams with up to .550 lift.

The valve springs on these heads have 115 lbs @ 1.900" installed height and 240 lbs of open pressure at .550" lift which is the max lift spec as well. Heads are sold each.
