As of Fall 2024- please allow 2-3 weeks for fulfillment if out of stock. Please email info@frptuning.com for availabiity.  To minimize issues with quality of castings, we will source all cores used in the CNC Program.  This is for a pair of CNC ported heads, with castings included, complete with reconditioned OE valves and aftermarket springs. We use an aggressive valve job for maximum valve clearance and extra shimming on PAC springs for max effort setups. We went 11.36@118.5 at 4500 lbs in a 8 speed regular cab Ram with these 5.7 heads.  The 6.4 heads are meant for pump gas applications and or applications where a big combustion chamber or lower compression is desired.
