If all you are doing is a gasket match, just go on summit and buy this and do it yourself.

When you get into real porting work, it is very easy to screw up if you don't know what you're doing, but a gasket match is quite easy, and for what it would cost, you're better off just doing it yourself.

For $1500 you can get Dalke to put you together a set of big valve, ported/polished heads that will support as much HP as you can throw at them.

a good port and polish job costs about 700 bucks. mine were 500 bucks but I know the guy personally and he cut me a deal. the machine work is expensive. it was 100 to hot tank and resurface. 380 for the new guides and seats. another 200 for the valve springs. 100ish for the valves.

so figure 13-1500 for race heads. not including the head gaskets, head studs, etc..

don't go for the cheapest guy in town to port your heads. chances are he's cheap for a reason. quality costs money. having a guy that KNOWS what he's doing and has been doing it for a long time is key.

The guy who is doing them has been doing them for years for the compmany I work for. He is retired and does it on the side I found out.

Home ported I got 225 186.

They were tested 4 times in cuts at 500 lift.

Intake backed off to 216 and stayed thru 600. Exhaust keep moving in small increments to about 194 at 600.

20 plus hrs., the right bits and a compressor that kept coming.

Testing, machining and valve work $400.00. (includes new spring perch)

I would suggest a minimum of $1200.00 that probably moves towards $1800.00 for someone to put in the time, expertise and equipment to pull numbers.
