Ported heads

I'm about to send my heads out to get ported. I've done a bunch of research but I still don't know where to send them. I don't want to spend over 900-1K.
Where would you guys recommend?

I was looking at

Fuelmoto
Bigboyz
Vee twin
where else?

I'm looking for the best bang for the buck. I don't want to spend money that I don't need to. This is on a 13 RG with Powervision,V&H propipe,Woods 555 cams.


Thanks in advance

Not sure about the money, but sure about the performance and service at TMan Performance. They are known for the performance work, especially with their heads. Check them out here: http://tmanperformance.com/. I am also running their 555TQ cams and they are awesome.

Word of advice, don't pick one set of head over another just because one says "CNC" and costs twice as much.

Head porting is all about getting the proper size, shape and finish in the right places. The trick is in getting the right port and being able to repeat it. You can get an awesome porting job by hand, it just takes longer and is hard to get it the same time after time. Repeatability is where the advantage is in CNC porting. A piss-poor port is a piss-poor port no matter what was used to cut it.

This is not to say there are not CNC heads that are not WELL worth the money, there are, but they're just as hard to find as the really good hand ported heads.

Do some poking around and reading, you'll find some that consistently float to the top.

Branch O'Keefe is considered one of the best. They've done 3 motorcycles for me and I've been beyond happy with the results.

Don't waste your money JMO!!! The torque gain for the money is is not a good trade off. I did a 103 Stage IV on my bike with high compression pistons and heads that were ported and polished and the SE 259E cam 58mm Throttle body and 5.3 grams per second injectors and my bike didn't put out any more torque then my 103 with the SE255 cam with stock heads. The only thing I got out of the deal was less mpg and a bike that is not as good of a cruising touring model HD because I had to keep the bike in a higher rpm power band range.

Do a search on the forum and you will find 103 engines with a good low end torque cam putting out 105 lbs or more of torque and the 103 stage IV builds just doing 110 to 115 lbs of torque, not a big bang for the bucks.

Ironmark you are comparing SE heads to properly flowed heads. It's not a fair comparison. With your 259 cam and the big bathtub heads the gains are all up in the high RPM range vs low/mid. IMO you can't compare SE "Stage IV" to a real stage IV...

Properly flowed heads bring gains across the board when paired with the right cams AND won't trash the low/mid.

My 95" gave up no power off idle and big gains clear out to redline. Mileage was better than my stock 103. Mileage was even better when I dumped the EFI and installed a carb (close to 50 on the road).

Be realistic and honest as to how you ride and listen to the recommendations of the guy doing the port work. Success depends on properly matched components.

If you never spin the motor over 3500 rpm skip the heads and go with a simple bolt in cam and save money for beer.

I would stay with who ever you buy the cam from. Dragos likes Tman cams and probably ports to those flow numbers. Fuel moto if u like the woods cam. Or Tman himself. I myself would go with a tman 555tq, 555C, or a 600sm if your doing heads. Dragos or Tman are your best bet. Proven time and time again. Take your time and call these guys.

Agree here apples to apples . That been said T-Man and Dragos will both give some great advice and they are the experts. Do some reading and listen to what others have done and how it worked out . SE is bargain basement if you qaulity do some searches, there is some great products avaliable.
