Local is selling 799 heads and I noticed there were two areas areas on the head that has nick's on them. Can I mail them a bit or should I not buy these heads?

G Atsma

Use 'em! A light skim will take those out.

What about this picture of the bowl?

just make sure the valves are not leaking on that last one, pour gas in the chamber with head upside down and check ports to see if its leaking

Hope they are dirt cheap. It's too easy to find mint ones at $400 or less

And it could easily end up costing more than that to repair them depending on how far you wanna go with the repair.

If they're cheap have them shaved .005-.010" and make sure the valves aren't bent, lap them in (or better yet get a valvejob cut) and run em.

If they're more than $250-300 I'd pass though.

Im getting them for 75 bucks. I plan on milling them and hope it won't be alot to remove those nicks. I'm gonna get the valves worked with either a 3 or 5 angle valve job. I'm also going to do some light porting and polishing.

G Atsma

For porting, just do a good bowl blend. That's where most of the gains are to be had with these heads. And don't worry about polishing. Almost nobody does that anymore. Check all the CNC jobs that flow the big #'s. No polishing.

Tell the seller you think they won't work, but you'll give him the benefit of the doubt, and pay him TWICE the scrap value. (which is what... $15 or so for the pair?)

Then just bolt em up and run em. Those are in places that totally don't matter. Only thing is, if there's a burr of metal thrown up around em, grind that down flat REAL CAREFULLY so the burr doesn't keep the gasket from laying flat on the surface.

I can't do that to the kid. We both agreed on the 75. I'm going to get the heads milled. Don't want to chance anything.

G Atsma

Hey, he tried! lol! Seriously you're still getting a good deal. Those nicks will machine right out.

I did a few searches in what fluids to remove the varnish and carbon build up. Oven cleaner is out is the question due to the chemical properties harmful to aluminum. What about acetone or varnish remover?

scrubby pad and WD40 and with the work your going to do you'll be in the same ball park you'd have been in with mine. and you could have just bolted those on

Throttle body cleaner removes carbon fast and easy too.

thanks guys. I was able to clean up a lot of the carbon build up but the 2 exhaust valves in the center of the head has some hard pale white on the dish that I just cant seem to remove. I tried soaking them in acetone overnight and tried a nylon bristle wheel and it wont even come off. It even looks like epoxy of some sort? no current pics but its the 3rd pic in post #3.

I've used a wire wheel on a bench grinder to get that stuff off before. Or you can pick at it with a pick or small blade screwdriver.
