i just bought a zzp shorty header off of a fellow member here. i was looking at it today and say that i could make the ports a little bigger if i port them. has anyone done this before? i am not sure how much i would be able to port until i go through the outside any ideas?

 

bigger is not always better...

 

i tried this on an old header i had and the welds ended up leaking and cracking. i have to say that it wont help on a header made with tubes, only a manifold like the stock or GMPP style

 

ok cool i was just wondering. they will be left alone. thanks for the tips

 

it's an aftermarket header made like that for a reason. There are "gas laws" that you need to read up on as to why. That's why step headers make the most power.

 

hey ralli whats up? when do you come back to lovely offutt?

 

10 days. you gonna meet up? Looks like you are working on some mods now. Get that header on there, you'll love the gain from that.

 

i ported my hahn header no problems. not so much the gains but the smoother airflow

lol or i should say i had a ported hahn header
