Did you guys just gasket match the intake runners? If not(and you went bigger) what did you do about the gaskets?
The heads are identical so the SRT will flow as much as the NA head. Nothing different except for valve springs. The heads we did were for a NA application and thus we bumped the CR a tad and only increased flow to what was needed. On the SRT we would further improve intake flow and drastically enlarge the exhaust side to balance out the pumping.
For the NA the intake port has not been fully enlarged for gasket matching, but it is port matched to our ported intake. Going larger has resulted in reduced velocity and loss of power on the 3.2L NA.
