I was talking to a guy at work about his new mustang. It's an 06 but it got this body kit with the fog lights right next to each other in the center of the grill(i'll post pics if i find some). Anyway the pi & non-pi differences came up and I explained the swap then he asked "Well can you reverse the swap like put non-pi heads on a pi engine so the compression will be lower and more boost can be ran?" (pump-gas). And I had no answer, But I told him I would rather leave the top of the pi engine alone and build the bottom with blower pistons. But if someone was to do that would it work?

 

im sure it would...i mean u can put pi heads in a non-pi why not visa versa??
