I'm going to be changing my D15B7 head for a D16Y8 head and i know i have o buy a new head gasket set. My question is, does it matter what size gasket kit i get? I know you have to get the gasket set that's right for your car, but the thing that confuses me is whats the difference between 75.5mm Bore, 75mm Bore, 76mm Bore, etc. and does it matter which one i get?

 

Get the OEM haedgasket and you don't have to worry about it.

 

Do you recommend and good sites to find parts for D-series engines? Because every time i look for parts their mosly for B, F, H, etc.

 

Look harder. Getting really frustrating seeing people that can't find anything and I find it all in 30 seconds or less. Start in the FAQs at the top of the page.

 

Anyways... If anyone is willing to tell me the difference between the gaskets, feel free.

 

Get the Honda OEM headgasket and you don't have to worry about which size gasket to get.
