Carbed 454 Help Needed
I was out cruising the lake saturday, and was going in to a turn, and the motor made almost a growl noise, but not in a good way. It didnt feel like anything was wrong, and so I tried to put the throttle back down, and it would go over 2500 rpm at full throttle. I limped it back to the dock, and got to looking in to it, and on the starboard side, the #1 and #3 cylinders didnt feel warm, so I dont think I was hitting on all cylinders. When I pulled the plugs, those two looked pretty shot, and the #3 had water on it. Im guessing blown head gasket? Does this sound right as far as a preliminary diagnosis? Is there any way to be sure, are there any tests I can run to be more accurate? Thanks for the help in advance. Its a carbed 454 out of a 92 Outlaw if that helps at all.

as stated very unlikley, more likely as stated in other post back wash from a quick slow down with silent choice open, head gasket
just tring to figure out what the "GRAWWWWL " could of been
