We have a reskinning-tumbling process. Have done thousands of intakes, valve covers, trans parts, blocks, heads, etc. A wopping $120 plus shipping. Meets NCRS standards too.

Here's a link,

Bill, is that yellow "tinge" from leaking fuel..??? I have seen lots of aluminum intakes with fuel stains, but that looks like the whole manifold is tinted. For spot cleaning, I use a little spray carb cleaner or brakeleen...spray it on rag and try wiping a small area and see how it looks. Don't spray all over the engine as these things may take paint off...I have also used a small brass brush with something milder like wax & grease remover, WD-40 or Simple Green...the brass brush won't hurt the finish...go slowly and see how it works. You may want to remove the carb, plumbimg, etc....tape off the valve covers, painted areas of the engine and kind of secton off the intake while you are cleaning...don't forget to put some tape over the carb area on the intake. Good luck...

PS....one other thing...check the bottom of the accelerator pumps and other common leak areas on the Holley...I know from experience they can leak and cause this kind of problem...if in doubt, call Eric Jackson and have him go thru it while you have it off the car...he does GREAT work.

Manifold looks like it has been cleared They often turn yellow like that.

Looks like a cleared intake. I see alot of street rods and street machines that people do that to. The enamel from the the clear gets hot and turns color. I am also not crazy about a bead blasted only intake. That is not the right look to me. Brass brushes are less abrasive. JMO

why are you yelling?

The clear coat has yellowed from the heat and time... never clear an aluminum intake...

[The Body God]

The best solution is to take the intake off, if it's cleared, get that stripped off chemically. A blast cabinet using "Glass Bead" only NOT sand, and blast it. I have had a blast cab for many years, I always use Glass Bead because it cleans without pitting, which is what typical silica sand does. Glass bead is quite pricey, $5.00 bag of silica sand = $50.00 of Glass Bead, but it will give you that like new appearance.

I had a pair of COBRA valve covers on my Shelby...I bead blast the crap out of them buy every time I even TOUCHED them they would get discolored...even the moisture from the blast cab would leave a 'trail'

So I got them as perfect as i could...and I fogged Eastwood alumina blast on one of them...couldn't tell the difference except the painted one looked PERFECT.

I later found that when it got dirty..a quick mask job and squirt of just the nasty area made it look perfect at shows...
