455 lifter bores
Can the lifter bores in a 455 be bored to accept roller lifters from a 307? It seems that roller cams aren't much more expensive than a flat cam, it's all the other stuff that goes along with it that costs the money. (roller lifters, cam button,etc) Also will beefed up 5A heads work on a 455? Will they work in conjunction with a roller cam? What kind of compression would they give me?

What about a set of 4A heads from a 403? Would they be a better choice?

You're right about the smaller ports and valves. My reasoning behind it is to bring the compression up so I can run E-85. I can put bigger valves in and I want to try my hand at porting. If I tear up the 5A heads there's really no love loss because I still have the E heads that came on the 455. I don't want to raise the compression with just the pistons because there is a rumor that they are doing away with the sale of E-85 in Missouri. So just in case that's true, I want to be able to put a stock set of heads back on it so I can run 89 or 91 octane without changing the pistons too.

You're probably right Joe. If I go searching for these 350 heads in a salvage yard, what would be a good price for good cores?
