It is an NA build or forced induction. If it's NA, what compression pistons are you running.

 

I saw a thread a while back before I was a member here where a guy fully built his motor without boost and got some serious track times. I can't find the thread tho.

 

I could use that information as well.

 

I recently built my motor and have had it back in for about 3 months now. I put high compression CP pistons in, Manly Rods. Race main bearings. 280 duration cams stiffer valve springs ARP head studs and Cometic head gaskets. I had the line the goes from the bottom of the radiator to the thermostat blow of because the clamp wasn't on quite rite and it overheated bad. It always overheats now. I changed Radiator and thermostat. I did a compression test and one cylinder has less compression and its leaking into the coolent system and pushing the water out. How common are cracked heads? I just got done pulling the motor back out and stripped it down and pulled the heads. I'm getting them pressure tested

 

 

 

I'm running 11.0:1 compression and N/A build with nitrous

 

How much power without nitrous.

 

Just curious. Those parts come balance?

 

What y'all think?

 

I50 shot

 

Unfortunately no
Now we just plastidip everything and wait for the XXRs to fall apart

 

Yes

 

Awesome! When I did the headgaskets on my car, I followed the FSM procedure and removed the oil pans. I see you you used a different technique. lol I'm just wondering if it's hard to do like that and will you be assembling with the oil pans on too.

If the cylinder was pushing that bad into the cooling system and you didn't see and clear indication upon dissassembly of a failed HG, I think it's safe to say you do indeed have a crack in the cylinder head. I'm not sure how common cracked heads are on these engines but it seems like almost every week we get a new thread in the forums of someone trying to diagnose an overheating issue and usually have symptoms of cylinder pressure entering the cooling system. I think it's safe to say that there not all headgasket failures.

Is that a revup engine and what are your HP estimates?
