Im going to be buying a low mile import from Japan Ea81. How Do I tell if it is a big valve or not.? I heard that 84 and up are big valve, I dont ant small Valve. good price though 429.00 free shipping nextday

Most likely it is a large valve head.I think 83 1/2 was the time they started to change over to that when the hydro ea81 was starting to be introduced.No definates unless you can see the valve covers and they say the "Do not adjust" sign on them.

Right on. Cool. Yeah cuz thats what I had in my car before. And I liekd it. my friends brat has small valves, and it just seems to lack the tourque that mine has, and were almost identical in engines. hot coil, and weber. I would ove to find a way to make headers for my ea81 gos that would be sweet
