With whatever head you run you should do some cylinder Bore Intake valve chamfer work.

Here's a picture of a iron head that started life with a 1.96" valve and then fitted with a 2.02" valve .

The wood in the first picture represents a 350 Bore at .030" over, the second picture is shows the chemfer that's needed to get that 2.02" valve unshrouded a good amount.

Steve25...Do you know how many cc's that chamfer added?

while this is a good practice, it was the exhaust valves that made contact.

I have the CC s noted at home so I will have to check for you later, but if I had to guess right now I would say 3.

Your Exh valves kissed your pistions, not your cylinder wall is what you posted, no?
I don't see what that has to do with a Intake valve chamfer I gotta say!

in retrospect, i dont see how cylinder chamfer has to do with the exhaust valve hitting the slugs

its already ran with 2.11 intakes and i dont see any contact what so ever.

but while i needed to retort to your comment, i do agree with you
