Gen 6 Heads on a Mk 4 Block
 

Can you guys help me out here. I am reading several different things on here, much of which is 10 years old!

It seems I can use Gen 6 heads on a Mk 4 block if I use the correct head gasket (on a 502). Is that correct, and if so can someone point me in the right direction as to which HG I should use

That being said, I just finished reading an article about converting from Series Flow to Parallel Flow by drilling the block using the Gen 6 head gasket as a template for the extra 3 holes. If I do that can I then use Gen 6 heads and Gen 6 head gasket as is?


EDIT - also - my gaskets that were leaking were "Performance Marine". What is the take on that brand? From the conversation on here it looks like Cometic or FelPro at the minimum....

This might be more quickly answered in Q&A section
