if the chamber is in fact too small, then just open it up, unshroud the valves to start with, then cc and see how much more you want and just do it.  hell nikie didnt get where they are by sitting there wishing they could fly through the air.....they had to get pumped first. I see zero issue with using a copper head gasket. and I wouldent run them with out them. dont go wide on the deck clearance,just do the needed chamber work or send them to somebody that can. not realy that hard to do..if you have the stuff to do it with. |

Those dished pistons and stock chambered heads would be great for boosted apps.

This! ^^^
Take advantage of the cylinder pressure and make some power!

These are factory piston to 11/1 compression to run pure ethanol.
Personally I don't like ethanol ...at least not in my cars 😀
By the way, we have here an imposed quota of 27% (E27) in the gas by the government, no pure gasoline from gas pumps.

| Pistons look nice but not so keen on running E85 |

Those are sweeeeet heads!
So what seems to be the issue of using them? They will work fine.
Just measure your chambers and top of pistons to figure out your compression ratio. Go from there. |

It will run, but without matching c/p you will end up with .5 inch area of no fins on the top of the cylinders - should expect an increase in temps... |

I have a nos Brazilian longblock engine with those heads and dished pistons. The thread I've asked about it years ago is linked to on page one but the pictures got photo..ucked. Still stand unused in a corner of the garage, but now I need a new engine in my pickup (1600) so came to think about it today and found this thread. If I read the mahle chart correct compression with dished pistons is 7.5:1 and were used with gasoline?
I've also read that they were fitted with dual carbs when used in Brazilian type 2 is that correct? Do you think a dual setup of kadrons or idf40 (what I have) would work or are they to big for the stock engine?
