Huh? I just got confused. Are you saying I should just go with a S14 SR to replace the S15 SR? I was talking about just swapping the block out. Or are you saying that the s14 block is the same as the s15? Im sorry for not being well spoken on the subject and thats why I'm here. My miss-understanding comes form (and I'm probably wrong) that a short block is just the block itself and a long block would be a block with a head.
