(We are partnered with Precision Porting for the GP, and they providing the heads completely Hand finished)
Here is what they are
We are starting with bare castings .
Complete specs and pricing below:

Your choice of 205 or 225 CC Runner Dart LS1 new casting heads.
Completely assembled and ready to bolt on with the best parts and coatings available, there are no shortcuts taken with these heads.
We have made them with the finest quality products because we like to ensure our customers have both performance and longevity.

Valves:
They come with brand new 1 piece stainless Ferrea 2.02" or 2.05" Intake valves and 1.60" Ferrea exhaust valves.

Springs:
They will also come with your choice of brand new springs from both popular spring companies.
The Comp Cam 918 beehive springs (recommended for up to .600" lift)
or
The Crane Cams Dual springs, 144832 (good to .650 lift.)
There is no cost difference between the two, and both will come with new Titanium retainers and new hardened locks.
These are secured in place by new ID Locators, which keep the spring in place and prevent it from moving around, ensuring good high RPM performance.

Machining:
They are given a full competition 3 angle valve job, lapped
valves and tested for combustion chamber and runner volumes.
These specs will be provided with the heads, as well as a flow sheet showing intake and exhaust flow numbers.

Hand work/finishing:
All intake and exhaust runners will be completely hand finished to provide for better airflow and performance.
This includes blending the bowl into the short side radius, and the entire runner as well.
Coatings:
All combustion chambers and valve faces receive our thermal
barrier ceramic coating which prevents detonation, keeps coolant and oil temperatures down.
This also makes more horsepower by keeping the heat where it belongs, in the chamber pushing down on that piston.
These coatings are permanent and have been in use for years on many customers corvettes, and we have had exceptional results because of it.
This process alone cost about $300 if you went to have it done seperately.

Final Assembly:
They come shipped to your door ready to bolt up,
All you have to do is put your rocker arms on.
We have already machined a newly clearanced rocker arm bar so you only need to put your rocker arms on.
We do request that you send us back your original rocker arm bars so we maycontinue to supply them machined for future customers.
