hey my friend is building a 2.0 6 bolt and was curious if he can use 7 bolt pistons on 6 bolt rods. i know the 7 bolts are higher compression and they look similar. but idk for sure if they will work. im to lazy to do any research on this old ass laptop so any info would be greatly appreciated. thanks.

oh and are the 7 bolt 2.0 and 2.4 oil pump and water pump interchangable? the 2.4 is a narrow block.

thanks in advance for any help
