White smoke!!

Thanks for the answers guys. I will do the compression check first thing.
I suspected just the head gasket and I hope that is all it is.

I can take a good look around for cracks and anything else out of the ordinary but is there anything in particular I am looking for? Where are the heads likely to crack?

The compression is 10:1 and the car spends alot of time between 3,000 and 4,000 rpm. Is a Felpro gasket going to cut it or should I look into something else?

Should I put it on dry?
