Wanting more power. Any ideas?

[AJ Bolen]

I was given a set of heads off a stock 2013 street glide. Im thinking about getting some work down to them and change my pistons. I have a screaming eagle race tuner,Mac 2 air breather, adjustable push rods, Fueling reaper 265 cams, Vanes&Hines big radius exhaust. HP.93 & TR.103. I have heard that the 103 has good heads but they just need to be cleaned up. also the flat top pistons are junk. What yall think about pistons and head work?

Uh Oh, here we go . . . . .

You will probably get some better replies over in the TC engine mod section. I've never heard anything bout the stock flat tops being junk , but then again, I aint no expert. I'd guess some work on them heads and a little compression bump , and a tune of course and you should feel a nice improvement. Whoever does your heads should be able tell ya if the cam will be good to go, headwork and cams kinda work together, you want em to be complementary to each other and work as a package, pipes work into that equation too. It'll come down to what kinda gains your looking for and how much $$$$ you want to spend. There are a few good professional cylinder head guys over in the engine mod section, they will give ya some good options.

Call Bean at Big Boyz. He'll fix you up.

Just wondering what's wrong with those numbers? They're pretty respectable that make your bike very ride-able and still deliver great reliability.

just have the heads ported and set for compression.
you got a nice stage II going there.
if you really want a gain ? you will need a cam swap, and the heads ported and cced to get the correct compression.
do the heads and keep the cam you got now,,, feuling 525 judging by the numbers? and gain 5-6 hp/tq swap cams and set compression maybe 10-12 hp/tq.
the flat top pistons are fine,to 10.0:1-10.2:1 compression. your at about 9.4- 9.6:1 now.

Cheers!

The old rule of thumb was gain 1 hp for every 10 lbs you lost. Maybe you should buy the bar and shield salad bowl collection.

I am beginning to despise the term "clean up"
The process can be laden with a whole bag of atrocities. Plus the stock heads do fine for very mild applications. The idea that HD screws everything up and we need to "clean up" their mistakes is flawed. We can increase airflow though. That can be done with stock valves but barely and in my opinion the ends don't necessarily justify the means. If the heads are coming off (gaskets and labor) why not put in premium parts including valves and guides for close to the same cost or a little more? Now we are at 103" and bigger not 95" as commonly. These motors respond to more airflow and choosing the right cam to go with those heads can change the personality of the bike by a large amount. The stock pistons are fine for all but very high compression.

So the question becomes "how many HP is the ol' lady worth?"
