Review on Hedman 69230 Chevy Pu Small Block 4WD: Unleashing Precision Performance! by Keith Desjarlais

They came as advertised and fit quite well. Headers have always failed, but this isn't like the ones I've used in the past. I had to machine the bolt holes on the driver's side head to get the bolts in. The kit also did not include spacers for use with the air conditioning brackets on my '84 K5 Blazer. Nothing wrong with that, but other headers I've bought in the past have had them. They work well on serious off-road vehicles as they detach the front struts without modification and are short enough to rotate the passenger-side to driver-side tube to clear the front driveshaft and transfer case. Keep in mind that you need to remove the launcher to install them. I would recommend going back with a 90's Camaro LT1 starter for 153t or a 95+ 454 truck starter for 168t flywheels. Their smaller size gives better clearance and helps prevent heat dissipation as well as higher starting power.
