Gen3 HEMI Engine BH2 Performance Valve Spring Kit by MMX and PSI

New product!

MMX BH2 Valve Spring set... This race valve spring kit is developed as the next step in our HEMI valve spring lineup. The OEM cylinder heads with large, raised valve spring boss make a dual spring nearly impossible to use. After working with PSI Springs, we can bring dual spring pressures to a beehive spring! These springs are made only for those wanting to push the envelope on RPM, and boost pressure. This is an application specific part, we recommend reaching out to byron@modernmuscleperformance.com first before purchasing to verify this valve spring is a good fit for your combination. (Example- Most sub 7500RPM combinations with shelf camshafts, lighter valves, and stock rockers do not need this spring and should use a PSI 1516 spring instead) Do NOT use this RACE spring on a near stock engine. Too much valve spring pressure is a BAD thing when it is not needed. Not recommended for use on OEM style lifters –  Recommended for only Johnson lifters, or other aftermarket lifters.
