Default Is 15 psi between cylinders acceptable ?? on Compression tes

Just did a compressions test - 2wd cossie saph

got.

145 psi
140 psi
130 psi
140 psi

Have got a head gasket leak so it's possible that this could cause a variance !!

Is 15 psi an acceptable difference ???

Also is that compression ok ??? is it a sign of a warn engine ??
Any help would be greatly appreciated.

Some good info here: http://www.pumaracing.co.uk/comp.htm

Did you do a dry & wet test, and was the engine warm?
