Yes. Which one is used depends on whether the subject of the sentence is singular or plural. If, when used as a conjunction, is never the subject of the sentence. The only time it can be is when the sentence is talking about the word if. A simple example is the sentence "if is a conjunction." A more complex example is the first sentence of this paragraph. In both these sentences the verb is singular because we are talking about a single if. In the sentence "too many 'ifs' can spoil a debate" spoil is plural because there are a number of ifs. The preceding paragraph may be a bit of a head-banger, but the good news is that it's maybe only once per million sentences that if is used as anything but a conjunction.
