These heads are stock[no stages done yet] in my 117ci build and i am running andrews 54cams 10.7.1 comp.
If i switch out cams only from andrews54 to TM590 do you think i can improve better in performance or should i stages done on heads and what stage would that be?

current numbers 120hp/121trq.

Wow that is a lot of squeeze for the motor with that cam.
Those heads respond very well to proper port work. It does not take a lot but out of the box they are all done climbing in flow past .450 IME. Not hard to fix that. With the Tman cam I would not expect much more than you have now until the heads are reworked.

[RoadKing04]

So then are u saying i can keep the cams i have in their now but rework the heads?or are u saying change the cams and rework the heads also?

Your over the top on compression with that 54 cam!! Holy spark-knock Batman!!
Wonder you haven't pulled a ring land off the intake side of your pston(s) yet!!
If those heads were brought up to speed, to their true potential, and you installed a Wood 8, at that compression,
that would be a scorcher, pushing the torque off into the 130's, as most good running 117"s traditionally/historically show.

I have taken the bike to 3 different dynojets unlike most won't do to back up the numbers that they post on these forums.

Dyno[1] PRIVATE SHOP
122HP/130TRQ

Dyno[2] HARLEY SHOP
115HP/125TRQ

Dyno[3] HARLEY SHOP[DIFFERENT]
120HP/121TRQ

Now Hillside the intake valve of these heads are [2.080 diameter],exhaust valve[1.623],combustion chamber[98cc] what would u suggest reworking the heads? I like to ride low to mid-range so after the heads were reworked would you stay with the 54's or my choice of either TM590 OR TM625?

[HD Street Performance]

Ah yes hp and a money role is all you need...
Just kidding, I am not pushy and based on what you describe you can get there for less
You have too much compression for the cam right now and it is likely pulling out timing automatically. This does not help power or torque.
If it were mine and low to mid range torque were the goal I would figure out if the compression is really that high (compression test), if so lower it and keep that cam, then get it tuned optimally and there is no way to know if you are getting low to mid range you want if the pipe is not optimal to make that happen. Your pipe choice is not stated..
A Supertrap 2 into 1 will help there. If the compression is in line then just run it. The cams you mentioned will help you achieve the goal when everything cooperates.
Save your money. Headwork will not effect low to mid range you describe, 4k on up will be helped but with that cam at 117" it will have short lungs on top when the heads are just starting to work.

Deweysheads thanks for your input as well.Here are some things that i left out,those numbers were with the thundermax autotune i am scheduled in the morning to replace it with the se pro race tuner and get it tuned.The exhaust i am running is 2-1 bassani B1 road rage,52mm TB.

I'd be leaning in the direction of the 2.120" Ferrea.
We favor a lot of the Wood cams, but that .625 you mentioned is a darn good grind.
We used one this past winter in a 107"er. Runs very good.

Just got home from the dealer and the numbers are 120HP/127TRQ. The bike has good response on the throttle its not running as hot so fast now but with no stages done on these heads that number ain't bad but it can be better i would assume with a different cam and stage done to the heads and that is what i want to get ideas about without dumping alot more money.

[HD Street Performance]

Many have fitted a Supertrap to the Basanni headpipe with success.
If it is not pinging run it and call it good.
No money, zero cost.

[RoadKing04]

I had a good talk with my mechanic and he told me that if it was him he change the pistons from ross to the screaming eagle pistons adding 20* done by axtel to match those heads and put my s/s 640 cams back in the motor,he would then bump the compression up to 11.0.
Now she rides nice,pulls great with the 54's at 10.7.1 comp but he feels the 640's would rock if we did 11.0 comp and did SE Pistons with a 20* added.

[HD Street Performance]

625 S&S is a better choice for a 116

[RoadKing04]

I am trying to make less chages as possible when changing the cams from these 54's i have in their now.If i get the s/s 625's what changes would i have to make versus all the changes i would have to make running the 640's?

[HD Street Performance]

If your heads are stock, meaning nobody has changed the factory specifications the 625 will likely bolt in. Seal to retainer clearance needs to be checked.
By the way if in fact those heads have a 2.08 intake they are a 103+ head not the stock 103 head used on the CVO 103

[RoadKing04]

Yes you are correct they are the 103+.So your saying i could in fact just swap out the 54's for the 625's and notice what kind of improvement if you are able to say?
