Horsepower Addicts, Delaware Cam and tune install
Dropped the z06 off Monday for a Cam and tune at Horsepower Addicts in Delaware. They sent a base line dyno back that evening
480/454
The car is stock parts and tune except for American Heritage Performance package 4 heads with PSI springs.
I’m going for their 3.7 Cam and a lightly used Halltech that will go on at the same time. Can’t wait to get the car back and see the results.

I don't believe so??? I'm unsure exactly what, if any, porting AHP does for the package 4 heads. I know I didn't pay extra for anything. I put extra cash into a better spring package.
I did do .020 milling that was no extra charge. So I would have, in theory, a slight bump in compression over stock unmilled heads

This is what I did. The only extra I paid was for valve springs
Package 4 Cylinder Heads (includes):
- Disassemble and Assembly of LS7 cylinder heads
- Performance Valve Job (show to add 5hp+ over the stock valve job)
- Resurface Heads (or milling of heads)
- Clean and Bead Blast entire head (so they look brand new)
- Hardened Aftermarket Powder Metal Valve Guides (Harder than aftermarket bronze guides)
- Stock Titanium Intake Valves Treated and Polished
- Ferrea Competition Plus Exhaust Valves F2042P (85 grams)
- New Viton Valve Seals and machined valve locks
