my engine is a 308 with a e303 cam gt40 cast iron heads w/ 1.7 rr and gt40 manifolds does it matter what hydraulic roller lifters i get or is there one that is better than others for my set up? also i the heads are from my old engine and i still have the pushrods... will they work or do i have to get a different size?
