curing a head in the oven

Im using some VHT high temp paint and it has 3 steps for curing. 250 -400 and 600 My question is at what temperature could the head warp?

i know that at 600 degrees for 45 minutes the seats will fall out .

not sure about warpage tho.

This is how and at what temps Pitstop Performance does it:

I don't the effect of 600 degrees, but that sounds pretty darn hot. Here's a link to OMR's temperature measurements on his engine. It appears that the head never reaches 400* under normal ops.

I put it in for 30 min at 250 then let it cool for 30 min then again at 400 then let it cool. its out side cooling off. Will see how turns out in a hour or so.

Hooper at Pitstop told me he uses gas grills to cook parts in.

I used that stuff on exhaust pipes. You can cure it with a heat gun. harbor Freight sells them for about $10.

They come out more tender that way but they don't have that smoke flavor.

Don't heat it to 600
