Just got done with a set of RPM heads

Here is the flow data for the EDDY RPM BBM 84cc heads. Mild bowl work, laid the short turn back, opened up the intake port a bit taller and put a 2.19" intake valve in it. Not a full port job by any means, but the flow is nice. This head in the right High Compression combo will make well over 700HP.
