ZZ4 And Fast Burn Headers

Randy Schonscheck · 09-13-2008, 10:09 PM

I have read that the ZZ4 and Fast Burn Cylinder heads have the exhaust port roof .100 taller than standard heads. Has anyone run into a problem finding headers that fit this port layout with 5/8 or 3/4 tubes. If not, what do you do???
Thanks!
Randy

No problems when using Hedman Headers. They make Headers to fit the taller exhaust ports in 5/8. 3/4 and 7/8.

No problem with the ZZ4 , its the fastburn . We elongated the header bolt holes and it worked ok on our car . We had Hooker 1 3/4 headers . Hope this helps . Mike
