I am know mechanical wizard or engine guru so this might sound off or basic but the Trick flow 270's are a max wedge port with 270cc intake runner and 74cc exhaust runners while these MP/Victor heads are standard port at 280cc intake and 100cc exhaust. Is this due to the Edelbrock/MP Victor being taller and have longer runners or is it the shape and girth of the runner when compared with the 270s? I have not seen these two heads next to each other and am just guessing the victors are taller with longer runners. If it is the length of the runner would the port velocity still be higher in the victors if they were ported to max wedge size? I see the max wedge Victors are 290cc intake.
