If someone can supply a nice clean bigport and small port head, I'll flow bench em.
Small ports have a smaller internal area with comparison to the big port head.
Obvious yeah, I know, but as the area of flow increases, the velocity of the fluid in the area (port in this case) decreases, but as a side note, pressure in the port is increased.
Small port heads have a higher velocity of fluid flow in comparison to the big port head.

how come you would only use the smallport head? i thought the rods are good enough to hold high rpm as long as you change the pins?
sounds good mate, if you do find out what the settings were let me know as i would be very interested to know
If Bill Sherwood is anything to go by then if using 304 or more cams a big port might be a better option. Obviously this is a pretty crazy engine though.
I’m guessing those hp figures are it the flywheel.
well a smallport has the best port velocity and also compression stock compare to a bigport also stock.
modify them both and still the smallport should have an advantage.
for a streetable engine i would always use a smallport.
my mr2 is a bigport and my trueno is a smallport and the 2 engines feel pretty different i think in terms of streetability and other factors.
toyota wouldnt switch to an inferior design

same opinion for a forced induction engine?
for forced induction 20v
hmm after this i now want ae111 quads + hks 264s... like the sound of 90 wheel kw
