If people don't think 220 is hot then what is hot in a street car?

Get the biggest radiator you can fit crossflow best and bigger pump like Jay said you could try lowering your fan starting temp too I would start at 160

You are not crazy hot, just warm, when matters

Hot idling-- fan or timing, usually fan.  I'd call fan volume the #1 issue I see in warm FEs

Hot driving -- usually radiator, exit airflow issue, pump flow or engine problem (or timing if advance very slow)

Stangman I think you are right, I corrected the post.

Very pretty. Is there an intake in the making?

We're talking about it. Doing some investigating. The intake has been a common request. Need to see if we can get one made and keep the price in a range that people think is reasonable. We're also continuing to work on our bolt-on rocker arms setup. Trying to drive the cost down on that.

If I couldn't get a .030 plus block i would consider the std block and sell the pistons you have .

Setting up the distributor so it has less mechanical advance, allowing you to run more initial advance, will result in the engine running cooler at idle.  Just part of the equation though because I agree with Jay's post about radiator size and condition.

What distributor? Does it have vacuum advance?

If it's a street engine with moderate compression, and you have good gas, like 92/93 octane, those heads can safely go to 40-42* of timing. That would help. Before spending a bunch of money, I'd double check your timing, making sure your TDC mark is correct. Retarded timing will affect temps at all RPM levels.

I run 40* on my 427 MR in my Mach 1, 500hp, all factory iron, stock brass radiator, stock shroud with Edelbrock pump, and it's fine on the street. Though at prolonged idle it will start to creep on a hot day. If I don't mix some race gas, it will start to diesel on shutoff if it's a hot day, so I use the clutch to keep that from happening. If it's an automatic, you can shut if off in gear. If I mix some 110, it's not an issue.

Maybe I’m looking at it wrong but the cracked part of the heads is the head bolt hole not the pedestal pad.
