318 with big valved or 340/360 heads

I always put in larger valves. It makes little sense to me not to. But - for a 318 port - I think the 2.02 intake is too large. You should be able to locate 1.88 intake valves in stock form that you can have a back cut put on, or pony up for a more performance oriented stainless deal. Depending on the shop, if they are capable of doing 5 angle cutter valve jobs - have that done. Then just gasket match the entries to the larger 340/360 size so you can run a decent intake. It's not perfect, but it will work.
