Recently purchased a 1990 Warlock 23 world class, wondering if anyone has run aluminum heads on these boats and if so how did it handle with the lighter weight at the stern? Currently running with a stock big block 454 and will be building a motor. With how light the bow area is was thinking of going aluminum heads on the motor to try to lighten up the stern of the boat, just wondering if it would handle better or be even crazier of a ride.

The only thing you'll notice is a power increase if you use a properly matched head .

Yeah already have the parts for build i was doing to drop in an 1988 cobalt condurre 223 but found the warlock instead. So you dont think the motor being lighter would help or hurt the ride quality of the warlock?

No , not enough weight to make a difference in ride quality . That's more a function of hull design . Throw an extra lady in the boat with you if you want .
