Bolts make it easier to remove the heads with the engine in the car. If we already have bolts to use there is no reason to go out and buy a set of studs.
The Chevelle put down 461 rwhp on just the engine. With the 250 shot it should be over 600 rwhp. I have no fear in the bolts not holding up. They have been for the past 6 years. But then again I'm also using a two bolt main block with a cast crank and running 10 flat at 133 with a 12 bolt rearend that still has the original axles in it.
