you need to use the correct head gaskets

the pistons to deck height are different and you need the correct head gaskets to rectify.

Mark at Lateral Performance can supply correct head gaskets

You have your answer above from Simon

Lots of cars use this set up its in no way uncommon, the head combustion area is different on the version 5 heads by a few cc also as mentioned your piston compression height will vary depending on what choice you make.

All of these can be correctly addressed by using the correct head gasket thickness.
