Stage 1 m8 heads are dismantled, cleaned, inspected, and reassembled to guarantee a secure seal for larger engine bore sizes. The heads are also equipped with high lift beehive springs that can accommodate cam lifts up to .600".
The Stage 2 M8 heads undergo a disassembly and wash procedure, followed by the removal of the stock guides. We then bowl blend the heads and replace them with new bronze taper guides. Next, a performance valve job is performed with the stock valves. To achieve the desired chamber volume, we weld the oil hole and deck and reassemble the head. Finally, high lift beehive springs are installed to handle cam lifts of up to .600 lift.
+1.5mm oversize valves (stage 3)
+2mm oversized (stage 4)
CNC head program for 17+ m8 engines these heads will be setup with beehive springs to accommodate your cam choice. This is a great addition to our street kit.
For optimal performance, combine these 1.5mm heads with a 62mm throttle body from HPi, our HP-67 cam, a high-quality exhaust, and a tune for your Milwaukee 8 engine. You can expect significant results, with a potential increase of up to 150/160 horsepower in a 124" combo.
The +2mm stage 4 heads on appropriate combinations have been known to produce over 170 horsepower.
Our Milwaukee 8 cnc head program is second to none. We utilize hand blending and complete all finishing by hand on the flow bench, resulting in unparalleled quality and precision. Our attention to detail is unmatched, making us the industry leader in craftsmanship.
