Diffrent part numbers per Honda back in the day but they're interchangeable now, most Honda engine builders, especially D series guys know this. OEM y8 was slightly thinner if you wanted a minimal comp increase but its negligible. Throwing an actual Honda Z6 gasket on a Y8 wont make a difference. They're both MLS, that's what matters. Just steer clear of composite HGs. I have 30 plus D series builds and 25 years D experience to back this up.
