This is a real quick two part question:

I have this head laying around:

I've got this engine I'm putting in a truck:

http://www2.towerhobbies.com/cgi-bin...?&I=LXGEE4&P=Z

now the question part:

1) will that cooling head fit on that engine and work correctly?

2) will I gain anything by putting the aftermarket head on the engine? (power, torque, etc)

I'm going to do some of my own research, any help you can give will be greatly appreciated..

thanks!!
