in a build like this, would the trick flow 240 heads make much difference?
[

All depends on what level the Eddy's have been prepped to and the cam lift used. TF claim their 240 head flows 318cfm@.550", ootb Eddy's are around 271@.550 if your lucky, also 78cc for TF's and if 84cc eddy's were used on that build it could screw up the CR if already on the limit for p/gas......my 2c's.
