we`re getting more air thru stock castings than SE heads,for a bolt on,youll get more than stock heads with SE heads,but decent porters will get a more street freindly,easier to tune,port job with your castings(hillside,baisley,our stage II or III heads,dan vance racing,sachs,t-man will all do a great job)dont know about every body else,but we`re not even taking in any more heads for a month

 

Gas Can has good advice. Its all a process and must be balanced. Or you will be walking.

I would go more with my engine. But---
Its a 08 FLSTF -

"B" engine
I have not gone into the bottom end.
I worry about the 20mm drive belt.

Those things limit how bad you can get reliabley and still have fun.

What I have done is enough.

 

here's a chart of an '05 flh 103" with screamin' eagle performance heads (they call 'em mcr now), se251 cams, roadrage pipe, stock t/b and injectors

paid a local shop $100 to do minor cleanup and valve job

sold my stock heads for $100

engine was built at heritage h-d ft walton, fl

not all dealers are bad

 

One more vote for Woods cams and aftermarket port job on your heads. I don't use screamin eagle stuff anywhere on my bike.

 

Baisley did a set of heads for me on my'07 flstf i had a 103 build done. Great heads.

 

Baisley does do good work. But this is a really old 6 year old thread!

 

I think he's made his decision by now
