Removed the heads today. Does Edelbrock stamp the MW Victor head with the Max Wedge name any where on the head to clearly distinguish the MW Victor from the Victor? Mine have victor 440 on the end of the head. The piston tops looked a bit dirty and #7 was the worst. #7 intake port is also the cleanest and the chamber looks different from the others as well.

The piston tops look worse in the pics than the naked eye. They do show some air flow patterns at the top, not sure what to look for there.

A few more. Do you see anything that stands out as being a sign of power loss issues?

These will be going to Steve Sanchez at Total Flow for inspection and some machine work. I think they need seals for starters. I'm not sure how far to have them milled yet, But will take atleast .045" for a 12.5:1 compression. I may take more, just depends.

7793 is MW casting; 7791 is standard port

There is a lot of buildup on your intake valve stems, IMO, but not sure from what.

That's what I told Dwayne. He thought it was not unusual. Ports look like they could be cleaned up as well. Doesn't look like a full port job with that slag in there. Why would the port with the biggest oil issue be the cleanest port except for the valve stem? first pic side by side. Thanks Brad

Is that daylight shining between the intake valves and seats, or some sort of reflection?

I’m sure Steve at Total Flow would be happy to do some additional porting on them.

Well, at least _I_ think it's funny...

They’re going to be at his shop anyway....... sooooo

I don't think that is day light. I will double check all of them. I really don't think I need the ports any bigger, Just better flowing and would cost a bunch. I think it would require filling in the floor of the ports and maybe taking some off the roof. Not gonna put that kind of money in them. Dwayne, as you said, they are a proven head. I just need to get the combo right and more compression imo is the first step. I posted up the pics to see if anyone could see any issues and you pointed out the possible day light. Thanks, I'll check that out.

Just checked the possible valve seal issue. No day light showing. I did notice all the guide seals on the exhaust pass head are leaking. These heads could use a good checking up.

What is your quench?The int ports can show reversion or rich fuel wash I think.I would think a dome piston is better than milling the heads.jmo.

Maybe a short dome, but I'm not interested in taking a good rotating assembly apart. Much easier to shave heads. The current quench was .049". Gonna tighten it up a bit, .043.

Use a dome if you want to make less power, otherwise do yourself a favour and have them angle milled. 0-.300" is possible with these castings. A dowel shift is a ton of work but pays pretty big dividends. I could go on and on. Depends on how serious you are of course just like anything else it comes down to $$$$$$$. J.Rob

Can anyone explain why all the intake ports have a bronze sheen or stain except #7, the one that leaked the most oil. You can spot it in the first pic as it is the one with the puddle of oil? Reversion, but why not #7?

This may be a stretch, but maybe the excess oil coated the intake not allowing the carbon to stick, except for the hot intake valve which carboned up?

Do you have flow sheets for those heads, they look like they could use more porting.

Thanks for that info JRob, but dont think I want to spend that kind of money on these heads. I will see what this intels thou. I dont know much about doing this.

Yeah, I have flow numbers. The ports were cnc by Hughes Engines. Measure 330cc, but they are long ports. Not sure, but cnc machine only takes metal where its needed I would assume.

With angle milling the heads he would need to re cut the pistons valve pockets.Correct?

Maybe, maybe not. It depends of course
I've had motors with good race pistons that had a hoop of clearances and other motors that didn't, you have to check to make sure
I had one motor that slightly bent some of the exhaust valves due to the valve pockets not being wide enough to clear the outer edge of those valves in those heads
I had checked the piston to valve clearances up and down, it had more than .100 every where but on the sides of thee those valves Clay is your friend when in doubt
