curious as to what type of gains to be seen?
i know that this question really kind of depends on a host of other mods but gimme what ya think anyways.

ballpark price from a local shop?

i've seen numbers thrown around for both questions, but they're generally pretty wide spectrums.

Did you ever think that there might be a valid reason for that?

If you want a ballpark price from a local shop... call your local shop and ask

Porting a head is not an easy job. When you port a head you can really mess it up bad if you dont do it right. A good machine shop with port and flow, port and flow until he archives his goal for the head. You can actually make the car loose power if you just go into the head and start grinding. A very good shop will port and port and when he reaches a point where he looses power he will fill the head with clay in that area and keep at it. Then you take a wax mold of the port and you match it to the new head. Porting is a science. Now you can gasket match and remove casting flash but doing so even then can create negative affects such as turbulence.

Now this would be a ridiculous head, but same rules really apply, maybe not to such a scale but are still there non the less.

Ask them how-much to port a big-block Chevy head, then throw yours their way if you like the price. It's so similar the the BBC head, they'll wonder if it came off the latest generation BBC!


Go beyond the "bolt-on".
