You probably already know GM does not make them. Unless someone has some laying around used your in luck. Other option is to go for merlins.

That is correct but the updated casting number is the 188. I bought a pair from Scroggin-Dickey Performance out of Texas. The specs are all the same just the casting number is different.

Thanks everyone i have plenty of cracked ones.

ScarabScoundroul how much for the one that is not cracked maybe this way i can make one pair for someone that needs a set.

i have decided to go with merlin heads. I am afraid that if this many are cracked their is a problem.

birdog are both of them cracked.

Yep, and more than likely the problem is stock Merc risers/manifolds. That's what trashed mine.
