Well its as simple as that. I still havent had my head port and polished for my engine rebuild and am looking for somewhere that is confident enough to do it, maybee even known for it. Any help would be great. Thanks

 

APE could do it.


cooper performance - they're known for racing bikes (drag and short circuit). that's who i was planning on using.




call them. talk to them. tell them what you want and see what they say

 

If your using aftermarket cams the head porting is a must do thing. The porting alone has gain 12 hp to rear wheel in this bike whit oem cams:
HPS Honda CBR900RR 954 Fireblade
Here is a graph of oem 954 head compered to unfinished ported 954 head. You will have to download it. It's a .pdf. Here is a link to fireblades.org
CBR 954 main and rod bearing help? - Page 3 - Honda Motorcycles - FireBlades.org
Couldn't attach it here. The professional that ported/ports my head said the oem heads flow is dead( stops increasing) at 8.3 mm of lift so my grinded cams would probably be worth 4-5 hp whitout the porting. Even the oem intake cam have 8.7 mm valve lift so you won't get everything out of it whit oem head. Only thing whit the porting is that it will probably move the peak hp rpm range up and even 954:s whit full exhaust will make peak hp very close to limiter.
