ISO a way to oversized valves on a budget
Is there a way I can go oversized valves for my d series by using for exp. f22a4, a6 or b18. I use those motor as examples because there're relatively easy to find at the junk yard. Thanks

First tell us why you need oversize valves, then we can maybe try and help. Just a suggestion, cause chances are you dont need them..

I think the deciding factor is going to ve the valve stem diameter and length. If those arent identical to a d series then it isnt happening
If theyre too big there might be a slim chance you can either get you valve guides modified to fit but im not sure if thats possible bevause then yous have to worry about the stems seals and other stuff

Well you still didnt give us enough info, but I still say you dont need them. Also when you ask people for help, you dont get to choose what kind of help is given. Saying "dont tell me about machine shops" wont make people very eager to tell you anything after reading that.
The reason I say you dont need them is because you should be able to make enough power on the factory valve diameter, and only a completely maxed out engine would really benefit from such an upgrade. Not to mention how much more difficult oversize valves makes in setting up the engine. You need to be MUCH more careful about P2V and especially V2V contact. For the amount of work and money involved in using oversize valves CORRECTLY, money can be better spent elsewhere..

That crook still owes me money.
OP - My personal experience is that his products are ineffective and do NOT work as advertised. Even if they did in fact work as advertised, your HP gains are not enough to warrant larger valve diameters. Run the stock sized valves, tune it up and see what happens.
