360 head trip

Veru nice thread!,great info.I port relatively conservative on street engines for this reason,I like big low lift numbers and velocity.Its amazing how well you can tame a fairly large cam street engine with the right heads and still make respectable power.

Very true !
Smallest port, with just the right cross section for the rpm range that flows the right amount of cfm to make the hp goal is ideal.
But a port on the small side/small cross section that still flows the cfm required with a wild cam motor will prove more torque sooner and basically band aid a nasty cam or mis matched combo while not sacrificing everything up top.

The right head or flow and cs etc is determined by the rpm range and or in a general sense the build recipe.

The head in this thread now has 2.02 int and flows in 260's, and its not even worked over much beyond what was done before the up size, just bowl blended the existing work.
