They'll fit. And you could also use a thinner head gasket from what ive heard. (But do not quote me on that)

if you are talking about p29/pm7 pistons and not flat pg6b pistons from 86-87 d16a1...

yes, they will physically work, but you will need swap to obd1 and run the proper tuneable ecu to run such a combination.

with the y7 head you will be in the mid-12's static compression.
