Compression ratio question

No.
I am not looking for just a change. When we built the engine we used the Pro Comp cast aluminum heads. The thermostat stuck closed one day and before I could pull over it got real hot.
It seems that it did not hurt the engine, everything looks right, good compression test and no leaks, but I am now not comfortable with it. With the new Trick Flow heads coming out late this year and they are billet heads form what I can find. I was thinking about changing the cast heads out for them. They have a smaller combustion chamber which would raise the ratio some. So hence the question.

Actually... he answered your question, .3 isn't much and might require a degree or 2 to be pulled from the timing. You won't have any issue nor power increase that you can feel from a .3 bump, the flow will be the power increase you feel with the trickflow heads...which if much greater, might add to the compression some.
If it got hot enough to cause damage you would know it.
You just want to buy the better heads and this is your excuse, don't ask us to back you up though...because If your engine or heads had an issue...it would run hot and or leakdown.
Saying you are "not comfortable" sounds like paranoia or materialistic "gotta have the latest" .
Btw billet is great and all, but I'll worry about that when it comes to crankshafts...not heads.

How green are you?
I'd rather read something like "hey I wanna go faster, I'm power hungry, will these heads work without it rattling?"
