CURRENT ESTIMATED LEAD TIME IS 3 WEEKS AFTER ORDER DATE TO SHIP YOUR HEAD- UPDATED 11/25/22***Looking for a completely rebuilt, performance cast iron head that is ready to bolt on- right out of the box? This is the head for you. This head is now fully CNC ported to flow 225IN/190EX CFM flow @28" (stage 4 235/200cfm), blueprinted and assembled with one of our very own dyno developed cams for unparalleled performance. Included along with the cam is our complete "top end kit" featuring Boport hi-flow oversized valves, matched springs, retainers, roller followers, performance HLA's (clearances set up by us), all seals and hardware installed making this head truly a bolt-on and go right out of the box. Choose from cam and valvetrain upgrade options below. PAC racing Beehive valve springs available with options below and recommended for all stage 2 and higher cams. These springs yeild 150# pressure on the seat and 350# open. The lightweight and higher pressure Beehive springs extend RPM range up to 7500+ rpm and reduce HLA pump-up. Standard springs are rated for 6500rpm. For 8000+ rpm applications we recommend our solid lifter option which includes a solid lifter kit, additional head machining for solid lifter conversion, spring pocket machining and individual setting of installed heights and the installation of cam tower straps to increase strength. ***If sending in a core, we recommend you have it checked for cracks locally first. In order for core credit, the core sent must be free of cracks and damage (rebuildable core).***
