Does anyone know if the valve guides and seals for the intake are the same as the exhaust? I know that the valves are different sizes, but are stems as well? (I bought new parts for the intake side thinking that they needed replacing when it turns out that the exhaust side is the problem.)

Thanks

 

the valve stem diameters are the same, but the exhaust stem seals are a different material than the intake seals. I believe this is because the exhaust valves get much hotter than the intakes. You'll want to buy the exhaust valve stem seals.
