The temperature gauge just kept climbing...383 in a Monte Carlo SS

[gbodytoys]

I didn't want to keep posting about this in the "what did you do to your G-Body..." thread...so...

Long story less long...

• Blueprint engines 383 Stroker w/ aluminum heads.
• Alternator pulley wasn't straight
• Twisted belt, which I ignored. Changed belts.
• Drove to a car show in Warren, MI...coming home, smelled rubber, ignored it.
• Got on the freeway, alternator wasn't charging, kept driving.
• Temp started to creep up, temp shot up, lower radiator hose exploded. Temp gauge went past 300.
• Got it home, changed the belt, changed the alternator (and pulley), changed hose. Car ran fine for a day in Telegraph Cruise. Stop and go traffic, freeway pulls, etc... no issues.
• Next day, car started cutting off at the light, but started right up. Then the car stopped while in motion. Pulled over...wouldn't start again. Got it home, started in the driveway.
• Checked compression. Low on the passenger side in the middle.
• Pulled headers, front accessories, intake, etc...
• Took the heads to work to see if they were warped (getting the last bolt on the passenger side head was horrible)...both are warped, didn't measure how bad.
• Machine shop said $105 to mill both heads.

Pics below of the madness. How do I know if the block is bad too?

In all seriousness as a precautionary measure I would probably get the heads magnafluxed first before doing any kind of Milling

With aluminum heads?

No, I just meant check for cracks first, wrong method for aluminum.

Before I would put a nickel into it I would get a look at the crank. At 300 degrees anything goes. The oil turns into water at that temp. There is an excellent chance that you need well more than a set of flat heads.

300 degree oil is fine, I do it all the time in my Camaro and so does everyone I race with.

Can I use those while the block is still in the vehicle? I'm not familiar with feeler gauges.
