As stated above squish is a little tight but in order for it to change check the lower rod bearing to see if it has up and down movement something had to change to allow piston contact. .043 is a good compromise on squish, usually when the piston contacts the head it will squish the ring in the groove. Check to see if it is pinched if it is you  have had contact.
