If you're looking for the best buy in LS7 cylinder heads then look no further!  The All-New PRC LS7 As Cast Cylinder Head is the ultimate as cast version of the GM LS7 Cylinder Head.  The As Cast version is basically a cast version of the popular PRC LS7 270cc cylinder head.  As with all PRC As Cast heads the heads will still get cnc shaped guides & hand blending!

These cylinder heads are available with standard stainless valves, hollow-stem intake, and titanium intake valves.  If you are going to run the stainless steel intake valves, we recommend limiting total valve lift to no more than .616" due to the weight of the intake valve.  Upgrading to the hollow-stem intake valve will shed significant intake valve weight and allow for additional lift.  The titanium intake valves will be the lightest choice of the three choices and offer the best lift possible!
