I have a 98 Chevy 3500 HD, 454 gas engine with older style Whipplecharger. Whipplecharger leaking badly from front seal, and engine has blown head gasket. Looking to have Whipplecharger rebuilt, but Whipple no longer services this older unit. I've heard about Jon Bond and Stegemeyer performance, but looking for recommendations closer to home in Wilmington NC. Anybody have suggestions?

Sending heads out & likely will be using Cometic head gaskets when it goes together. Does anyone know what kind of power is safe for the engine? Stock 454 as far as I know, about 150,000 miles on it. I'm not up to speed on these relating to how well the bottom ends will handle more HP than came from the factory. I don't know how much boost the Whipple has been adding, but will be adding a gauge when we put it back together.

Thanks in advance.
