Over heated the motor over the weekend and now it's a no start.
I have a mild built 351, in a fullsize bronco that races short course and pro area (Think tuff trucks)
I am not an engine gru, so I need help.
Engine is pretty much new with 3 races on it.

At the race this weekend, it overheated (I was in 2nd place and pushed it, I should of slowed down, but too bad so sad) to where it stalled on the track and would not re-fire.
In the pits I pulled all the plugs and sure enough, they were full of water, you could also feel the compression blowing out the radiator while I was cranking it.
I pulled the intake (Lighting lower, explorer upper) and did not find any cracks and the gaskets still looked good. I then did a compression check and had low numbers from 40-90 PSI with the intake off.
The head gaskets look 'meh' you can see some leakage at the rings, but not around the cooling ports.
I can't see any cracks at the heads, but I know you can't see a lot of them with the naked eye.
Only real way I could think of testing the rings was filling the cylinders with oil and seeing if they leaked down, they did not, is there a better way?
The piston bores don't show scoring.
I can't think of a way a cracked block would give them these symptoms, but I dunno.
All signs point to the heads, but I'm not sure I want to pay the $150 to have them looked at only to be told they are junk.
I'm very happy with the power it puts down, so I'm think either thinking flow tek heads or edelbrock heads 5023. (I'd rather put money into suspension then power)
Would it even be worth it to pay $400 (Guessing) for someone to restore these SVO heads if that's the issue?
