Yes, however the compression will be very very low, around 7.4~7.5ish not worth it. Race Engineering sells some dohc ZC pistons which will work better for your application.

Also, if you call SRP and ask them if there fi pistons for 4cyls will support over 400whp they will tell you no, lol... however they have been proven to do much more than 500.
