MMR now has in stock its upgraded valve springs for the GT350 heads. For those that did not know the GT350 head uses a Unique Valve spring, MMR is proud to offer 2 new versions, 1 is for those that wish to maintain VCT and 1 for those that wish to lock it out. Both kits are a direct drop in and includes features such as upgraded Chromoly or Titanium spring retainers. The factory springs have very low spring pressures (under 60lbs) which is not optimum for forced induction applications, the general rule of thumb is to increase valve spring pressure in relation to Intake manifold pressure so that boost pressure does not open the intake valve. MMR has spent the last few months testing and developing these spring packages to bring you the best valve springs available for the GT350 heads.
