which head are they referring to when they say vtec head?

i know that advertised compression is often different then the true piston compression..how about these?

 

That would be B16 at 42.7cc.

Let me know if you need help with other CP specs as I have specs not listed on their site.

 

CP sizes the dome according to bore size so that 84.0mm 84.5mm, 85.0mm pistons have the same CR because as the bore increase the dome needs to be a little smaller.

You can thank Darius of CP for this attention to detail.

take note everyone- rocket = good info

thanks robert... that compression question just came up because i've seen wiseco pistons and toda pistons advertised/claimed compression higher than what the compression actually was..and i'm pretty much set on CP pistons so thats why i asked about them.

edit: although 12.5 would be too high for my application IMO

 

they assume a 0 piston to deck height though... at least that is what i was told by darius
