This is a really dumb question but is there a difference between an h series header and an f series header? just bought an f20b and im tryen to figure out what to do with it. lol

Also what about the intake side is there a difference?

 

Different heads have the exhaust ports in different locations.

For example:

o o o o vs
o oo o vs
o . o . o . o

H23 ≠ H22
F22 ≠ F20
H22 ≠ F20 BUT....
H23 = F22

 

Thanks that does help. Im so use to b series that it didn't occur to me that the world changes in h and f. . . Well while im on topic is their any exhaust header that you recomend for an f20b Im not trying to do anything crazy just get out of that stock cast bs and make a little more power

 

You might check the Bisimoto header, but your best bet is probably something like DC Sports.
