Spark Plug Reading WTF

[GNDriven]

Does this plug look normal? Plugs from cylinders 1 and 4 look this way.
Spark plug make = NGK FR5.
Background = The engine is breaking up under fullboost (22psi). Could be a slew of issues I know. I am trying to step through them.
These came out of my engine after 300 miles. Engine was broke-in on these plugs. Engine is a built 109 w/GN1 heads. Fuel = 93 w/ methanol injection.
Turbo = new Precision 71 unit. EMS = Classic FAST. Thanks for the readings.

Throw some Autolite 103's or 104's in there. They seem to work best with the GN1 heads.
Keep the boost down until you get this fixed!! You don't want to be doing head gaskets. Check your fuel pressure and turn the Alky off until you get things straightened out. I would be interested to see what the other plugs looked like.

Just saw the Turbo you are using. Who's downpipe are you using? Internal or external gate? Exhaust housing ported?
That turbo should just be waking up at 22 psi

List your mods. cam, springs, etc

They look pretty good to me, maybe just a bit lean. Photos on the computer can be deceiving, and alcohol can really make reading plugs difficult.

+1 on Bryans's advice. Do you by chance use Mobil gas? We used Mobil gas in our cars and I noticed a build-up of gunk like your plugs show on every car we have, including daily drivers, when we use Mobil gas. Paul

Maybe this will help you read your spark plugs.

IF you look closely there is some brown flaky substance on them. Looks like corrosion possible. All other plugs did not have this bumpy texture. I am wondering if my heads gaskets are leaking coolant into the cylinders.

I did replace all spark plugs, but would like to analyze the cause of what would turn a sparg plug this way.

Is it only plugs 1 and 4 that look that way?
If so, they're companion cylinders on the coil. Maybe you've got some cross arching going on.
