Re: 2v or 4v
that 2 and 4 doesn't necessarily mean they are 2v or 4v, I have a set of 2v's with the same castings on them, another set has 3 stamped there instead. You will have to pull an exhaust manifold or your inlet manifold off to find out mate... You will know if they are 4v cos you could squeeze a tennis ball in the port if thats the case!
