I've talked with Zippers Performance about doing a standard Stage 1 or even just rebuilding to stock. Their pricing seems fair enough.

So where are you guys send your heads to for rework??

Zippers has some nice head work. We just installed and tuned stage 3 muscle103 kit for a customer out of Iowa he bought and brought down for us to install and tune.
Heads look great!!!

I've sent the last two sets of heads to Don at HDStreetPerformance. Does a great job and is really fair with pricing. My 110 heads came back flowing [email protected] lift and turned 132/138. My stock ported heads were a clean up from a previous job and so no flow sheets, but they managed 122/132 on my bike. Both are low compression 124s with mild 585 cams.

I took my stock heads to the local auto machine shop and for $100 (total cost for both heads) they cleaned up the valves and the valve seats checked the heads for cracks and checked the valve guides and put in new valve seals and springs and shimmed the springs to HD specs. I supplied the valve seals and the SE performance valve springs which I got from PC Pain.
I wouldn't put the stronger springs in again because they really are not needed in a stock head and they seem to have a bit more top end noise.
The heads perform great and there is no problems with compression and the bike doesn't burn oil and the work was done over a year ago.
Check out the local auto machine shops and see if they work on Harley heads if not you can go to Bullhead Auto Machine in Bullhead city they are on Ramar road and they are the shop that did the work on my heads.

Be FULLY AWARE that a valve job, is not the same from shop to shop.
We use Serdi/Goodon Tooling here for dead-balls concentric seat-forming with carbide single cutters establishing as many as 5 angles in the seat area in one cut, opening up the seat throat to the bowl area, and in some cases 2 angles on the valve itself, say nothing of cylinder head porting/larger valves/seat replacements/flow-bench work, setting stem protusions, valve to valve clearencing for large lift cams, and insuring proper seat pressure, etc, etc, is the work that really yields HUGE gains.
Kissing the 45/46 degree seat angle, grinding the valves, and installing seals is not the same.

if your just cleaning up your stock heads and you're not looking for performance heads then a good valve job and new valve seals will work just fine and it cost a lot less then doing performance heads.

I have all my Cly and head work done by a local shop,Pearson Racing,he is a motorcycle machine shop only,hes been doing this for over twenty yrs,his rates are very fair,one of the guys i work with took his evo clys to a auto machine shop for boring and when he reassembled his motor it smoked,they had no idea that they were supposed to use torque plates,me personally i would rather take my stuff to someone in the motorcycle field,do yourself a favor and talk to several shops to get an idea of what you want,IMO i would steer clear of any shop that tries to SELL you on larger upgrades with their heads rather than working with what you have.

I agree,steer clear of automotive machine shops

Some auto machine shops have been doing work on HD heads and cylinders for years and they have all the required torque plates and jigs to perform the work, you just have to check with the shop before having the work done there.
You would be surprised on how many MC repair shops use a local auto machine shop to do machine work on MC components.
Who did all the machine work on MC parts BEFORE there was MC machine shops??

Not all Auto shops have the proper equipment,thats why you need to investigate and ask questions,to answer your question as to who did the work before MC shops,well the clys that were cast iron were a whole different ball game as today to each there own,all i know is that my 01 RG ,all the cly and head work was done by my local shop and that 95 inch motor stood up to 60,000 HARD miles and it never had one issue and i did all the assembly of the motor,its all about who you feel comfortable with.

There's right..........then there is everytning else.
We do it day in/day out here, 6-7 days a week, with full shelves waiting to be worked on, not only for other shops, but private individuals as well in all phases of cylinder head work/repair.
We also manufacture/sell specialty cylinder head tooling.
Gotta' go.........work on cylinder heads.:)
