been having abit of a look on google images and found a 4 valve head to suit a yx engine are they worth buying im planning on putting the biggest piston i can in my yx160 so its like 180 upwards would this head be worth it over a ported 2 valve?
..
TO ALL of you 2 V diehards, 4 VALVES ARE BETTER THAN 2.....

I'm very interested to see how this performs, I would still like to have a go at building one myself. I just bought a milling machine, so I won't be spending to much money on mini's until the bank balance recovers!
