i will have to go and check that.the cats aren't very old do they stuff up much or would the water have wrecked it?
when i was putn the head back on if it was warped would i have noticed do you think?

If they are alloy heads, as soon as you pull them off 9 times out of 10 the warp just a little.
if that's the case get them machined at a machine shop as it saves so much heart ache!
I hope that helps.

You wont notice a warp in the heads. Its usually a very small amount. But can affect the seal. Get a straight edge and feeler guages to check for a warp.

so if they were warped it would have these issues?
it doesent have alloy heads just standard ones.

Cracked head?
Was it crack tested when it was removed? (there were cylinders with coolant in them, correct?)
