I figured I would start getting some things prepared for my new engine build.
The first thing I wanted to do was get my heads in check. I purchased a set of heads off a nitrous grudge car from Detroit. These heads went 7.87 @ 175 on 2 stages of nitrous. Being that it was a grudge car I didn't expect them to be perfect and I new they would have been abused. That being said the price was right and I get to do them how I want.
The heads are Yates C3's that have been heavily ported by Bennet Racing and were sleeved for 1/2" pushrods. They feature 2.125" / 1.6" stainless valves and 41 cc chambers. These heads have been around a long time but I plan on making them a real nice set.
The 1st process was to clean up the intake runners. When the pushrod holes were drilled for the larger pushrods they entered the intake intake runners. The sleeves were installed and welded from the runner side. On one head they ground down the weld a little half assed and on the other they never touched them. My 1st task was to fix that.
The runners turned out nice so I decided to clean and scrape the heads and take a few pics.
One of the downfalls of massive amounts of boost or nitrous is what happens to the combustion chambers when you dont keep an eye on your tune. The 4 corners are usually the ones affected but I can tell these have been hurt a few times. The area around 1 and 4 spark plug holes is seriously damaged from detonation as well as the quench area on 1, 2 and 4. These will be perfectly repaired and each combustion chamber will be close to identical.
I'm going to disassemble these heads tomorrow and get them to Matt to have the combustion chambers welded up. I will need to scribe the bore of the block onto the heads and then they are going to PKRE, Paul Klyzek Race Engines in Colorado to have the combustion chambers convcaved. It will open the quench area, let me run a better piston top and will tune much better on 2 kits significantly reducing the chance of detonation.
