Ever been bench racing with some buddies and come up with a build plan? Does it usually sound like, “I’m gonna build a (insert engine here) and I’m gonna run this intake, these heads, and it’s going to make reality times three horsepower!” Yeah…I’m guilty, and a lot of you might be too. It’s like fishing in a way…who can come up with the most believable story wins. When it comes to heads, the usual trump play is to break out a well-known, high-performing CNC-port head from a reputable company as the item of choice…but the proper response to that is to point out how expensive said heads will be. A quick cursory Google search pins CNC-ported heads for a small-block Chevrolet at about $1,500, depending on type, CFM flow, material, and of course source. You know what else $1500 will buy you? Another project car. You could go to the Vortec head, which can be found in junkyards or for sale by rebuilders for much less than that, but you will be down on power. Is it truly worth it to buy the expensive heads, or will that decision fail the cost-benefit analysis? Freiburger and Dulcich are back in the dyno booth, beating on the BluePrint Engines 383 Chevy to give you the answers you want!
