ok ive got a set of the cb 044 magnums with 40 X 35.5 valves unported as in straight out of the box/no cnc porting so, im wandering if i would be better off to buy all new 044's with the 42 X 37 valves and the cnc port job or to send mine somewhere to have bigger valves installed and either a hand or cnc port job? oh if it matters on what to do i have 2 sets of the same heads one on a 1915 with vz15 cam and 1.1 rockers and the other set is on a 2332 with c35 cam and 1.1 rockers but whenever i have to split the case on either i will replace the cams with a 110 and add 1.25 rockers |

A CNC port job is an improvement over none at all but it is not comparable to a good hand job.....you do call this Head after all. Give em to a porter & let him do his magic. Ive always been told a good bowl cleanup is worth HP. The guides need to come out for porting & going to bigger valves will run about 150 more. Wow....this sounds like something you hear on Dr.Ruth

Sounds like your going for torque and throttle responce. Big valves don't mean greater air speed. Go to performance-workshop.com. You want heads with great air speed Steve's ported 043 VW heads are going to have greater air speed than the 044s since the port volume can be kept smaller. He can also port your 044s. Call and ask to talk to Steve. |
