A few months back I bought a 59 stepside Apache it has a stock 235 in it.

Parts I have for it in the house are a 268duration cam from Clifford cam, Fenton dual headers and a fancy triple ace intake from a '54 vet

So, looking for lifters. Do the years matter? The 261 from '55 will fit or nah?
I'm under the impression that I need to cram 261 parts inside this 250 because of that intake

What about valves? Is there an "up size" that we can put in the head so it breathes bigger breaths? (I got vortec valves in my amc 258 can we do something like that with the 848 head?)

Any advice otherwise,
aside from talking me out of doing this build cause it's fruitless. ima do it out of spite snd have an evil truck
