reading comprehension ownes you so i will retype in kindergarten words for you.....
it is pointless to buy a cool head if all you want is more compression. have your stock head cut.... why would you pay 200+ dollars for a head that will leak, blow O-rings, and no added cooling properties when you can spend 35 bucks for machine work?
if you never have plans on going all out why waste the money? i paid 80 bucks to have a stock head machined for a 421 cub.......... no leaks no wasted money on something i didn't need etc..... your statement was ignorant and now you reaching for why "everyone" should buy a aftermarket head. all these company's did was make it so that dumbasses could change/ run different setups. wtf do you think ppl did in 87 when they ran different setups? or any 2 stroke for that matter? lol it's whatever it just burns me when ppl make retarded statements like " it's pointless to run a stock head"
