Average cost of rebuilding heads?
 

I am going to have to replace the guides, 6 exhaust valves, and possibly the springs (overrev).

How many hours does it take a shop roughly and how much?

Cory,

Prices vary quite a bit but IMHO, the question you should basking is "who can do a competent and proper job of it?".

In these situations, quality is much more important than price. :) :)

Some shops are all set up to resurface, machine the seats, R&R the guides/hone to fit everything on 911 heads; others are better equipped for other types of engines.

Call me if I can help. :)

Thanks Steve,

The shop I went to today I feel is very competent. The owner wanted to take about 6-8 hours to put in guides, hone, dress seats, and check springs heights/pressures.

Add in the cost of parts and I calculating around $1500 in my head. That is a little more than I anticipated.

I was trying to get a consensus of what these cost should be. :)

For that money they should be twin plugged. The last couple of sets I had done were around $600.00

$1200 for mine. Full machine on the seats to stock and mating surface clean 0.010". Everything assembled, cleaned, and ready to put on the engine. I picked them up, so shipping was not included. The company was Extreme Cylinder Heads here in FL. Great rep and Bill is on here, infrequently, but on here. He has some amazing heads he engineered and manf. for bigger engines :) RACE PORN!

That sounds more like it, thanks. :)

Will look into, thanks. I like RACE PORN... :)

It depends what your definition of 'rebuilt' is.

Just new valves, guides, springs, and valve guide seals cost over $650

Add in labour to:
- clean, strip, and inspect heads
- surface the mating surfaces
- replace guides
- cut seats
- shim springs to correct height
- vacuum test valve seating
- maybe install a few timecerts on the exhaust stud tappings

I think a complete overhaul is going to be closer to $1,200 than $600.

Call Bob at Anchor Atlantic Enterprises

Bob is a good guy to work with.

I gotcha, just used to American heads getting rebuilt for about $2-300.....;)


Will take note of, thanks! :)

EBS did a set of 2.7 heads for my last year. Off the top of my head:
-12 new valves
-12 new springs
-12 new guides
-install guides
-valve grind
-fly-cut heads
-etc etc.

I think it was around $1,100.

Thats a lot of work and more closer to what I would expect, thanks! :)

I just priced a set of SC heads here in Chas, SC at a very good machine shop. Price is approx $450 plus guides and seals.

I pay 600 flat rate (cdn) to have the heads disassemble, inspected, new guides, valve grind, sealing surface machined, bead blasted and reassembled. Extras would be any new valves required and the cost of twin plugging (300) if one desired.

This is the machinest the dealer and all the local independents use. I have head probably 8-10 sets done with excellent results.

It all boils down to hours X dollars plus parts. Assuming your machinest is knowledgable. The only variables should be labor rate......



Cheers

Jeff, what's is name? I'll be back in Vancouver in a few week.

Lance Hayward, www.haywardperformance.com tell him i sent you! :)

Lance is an excellent machinest, does great work including case repair.

Give me a shout when you are up here.

cheers

I would contact "cgarr" a user on this forum. He does head work and twin plugging out of his home shop. His prices are very good and the pictures of his work I have seen look excellent. He did my rockers and is a good guy to deal with. I know he has done several heads for guys on this forum. He is in Michigan.

Since I am changing out and upgrading everything I opted for EBS in Nevada. I doubt there are too many shops that do as much of this as they do.

Ah yes, my brain is finally out of neutral - Bob Magyar told me about Lance as well and had only great things to say.

Ted was a great guy to work with.

Kenik - Any possibility you can take my heads too?

I am planning on going in Feb, so if I do - yes. :)

Not bad, thanks. :)

I dont know the exchange rate. It sounds like a lot? :confused: :)

Thanks! Will look into. :)

Not too bad of a price, thanks. :)

I had my heads rebuilt by Carl's Place here in Las Vegas. They are a great shop and the owner is a fantastic guy (Tony Mazzagatti). To have the heads completely rebuilt with new seals, valve seats, guides and fully assembled with cams was $850. Original valves and springs were used. They looked brand new and I was very happy with the work.

Another thing to consider
 

Stock Porsche heads usually have three angle valve job on the seats. Stock V-8 engines typically don't. Three angles takes a bit more time to do properly, especially if other components are changed, like valves.

I also used cgarr for rebuilding and twin plugging my heads, I thought he did an excellent job and his prices were reasonable.
Highly Reccomend, Good Luck!

I used Competition Engineering (rec'd by Wayne), got great results, as has pretty much every other person on the board who's used them. I needed about 1/2 the valves replaced but the total bill was around $1800, maybe just a bit higher IIRC. This was including all new valve guides, pretty much totally rebuilt the heads. They came back looking like artwork. The turnaround time was not bad at all.
