i know clevelands are not #1 on people list in here but...
i have a brand new never installed set of intake manifold port plates for 4v cleveland heads.
they are to increase velocity in the ports withoutr sacrificing flow
and add torque on launch
for cleveland engines staying UNDER 7000rpms

if anyone is interested, they are $60 brand new shipped
i will sell them for $40 firm my loss is your gain
