Yea the 404s are too much cam for your build, although they have a beastly idlejust google crower 404s and you'll see what I'm talking about plus they would have to be degreed to try and dialout some of the big overlap they have, then you'd need adjustable gears to fine tune from there

Just stick with the 402Ts. It will be fine for your goals

 

thanks fellas
