Budget Aluminum Heads
Be careful here, because Silvolite does not make a forged piston. The parent company, United Engine and Machine makes forged pistons, but under the Icon brand. They also make hypereutectic pistons under the brand name Keith Black (KB). So be extra careful when purchasing. If it's an individual telling you they have Silvolite forged pistons, run, because there's no such thing.
Also if I were building something similar, I think I would look at the 440 Source Stealth heads. Yes, there are "better" heads for a lot more money, but those are one heck of a big bang for the buck.
