Aerohead racing heads concern

I can say in the future Ive had alot of experience CCing heads cause I did both sets another 3 times and got all anal on them. These are the readings.

84 79
86 77
86 77
84 79

I am sure these are accurate readings, no error.

They advertise these heads as having 86-88 CC combustion chambers.

Im going to call them this morning, without saying too much at this point Ill just say a woman sometimes answers the phone and sometimes a guy, the guy struck me as not being overly customer friendly, after calling a few times I had to ask the woman if there was someone else I could speak with and was informed that the guy is the guy.

Any thoughts?

Just called them and spoke to the guy, he couldnt have been nicer, told me he would pick up the head and ship me another matching the first at no charge.

I really thought this was going to be a fiasco but I was wrong
