[QUOTE="Orr89rocz, post: 3148656, member: 34347"] eh true... didnt really consider that. but still there are 4 inch bore ohv 2 valve heads for sbc that flow just as much as the 3.55 inch mod motors. then there are some 4inch bore sbc heads that flow a ton more than mod motors. even small block ford heads that flow more. the port size tho doesnt matter what bore diameter is. ports that are bigger feed more air at higher rpms so you neeed to rev the motor more. ofcourse more cubes want more air so you want bigger ports. mod motors can rev in the 6K's. pushrods with teh right heads with the larger port sizes will make power up there too. course i dont know that the port size is on the mod motors. 99+ pi heads are 159cc intake, dont know the exhaust. still i dont see a huge advantage of motors with ohc's. and that big mod motor is pretty impressive! but alot of that power could be contributed to the hemi combustion chamber which allowed for alot more flow than wedge type combustion chambers. if the two heads flowed the same, i bet it would make similar power [/QUOTE]
