Those are the "winters" big block heads. They were produced as a racing piece and where the shiznit in the 70's. Even against some of todays stuff, they perform well, esp the factory iron rectangle ports. I think the intake ports are like 295cc or so, and a C-shaped exhaust port. Of course, if you know your 088's perform well and are happy with them, the only advantage you'll likely reap would be the weight reduction. Depending on what's been done to your 088's I'm not sure you'd be blown away by swapping heads.
