Not sure if this is the right place to post this.There is getting to be to many forums now.Getting confusing.

Hi guys I need to get some advice.Currently I'm restoring a few mowers,but the one's that I'm up to now is the VC-160 Mark II & III.At the moment I'm up to doing the engines.All is going well except for the heads.Here I'll show you what the problem is.

As you can see from the one on the left,they are very dirty.Now if it was just moist oil on there then it would be easy,but it has been baked on so it is rock hard.How do I remove it?I'm trying to make these heads look like they are new again.I have tried using degreaser and that just shifter the top layers.Now I'm down to the hard crunchy stuff.Surely there is a better way than sitting there with a scrapper and screw driver, chiselling away.There would have to be some chemical that I could use.Please help me with some other faster and better way.
