which heads will work?

[mercpower]

Looking for a set of heads for a 1990 2.4 Merc 200EFI. Its a stock bass motor and lots of people have 2.4 heads of different variations and origins, but no one is sure if they will work on this stock motor. Thanks

Small chamber 33cc heads would work nice on that set up with 92 octane.

Thanks, I've had a chance to buy some two piece heads, and some "lost foam" heads, not familiar enough with these to know if they will work.

Get the 2.4 lost foam heads, they run cooler.
