PRC Aftermarket Casting 250cc LS3 Heads Shipping!
Guys we're shipping the new PRC aftermarket casting LS3 heads! Here's the info:
PRC Aftermarket LS3 250cc CNC Cylinder Heads
base price $2,199.99
item# 199-PRCLS36B250 Previous Up Next"
|Share
All Precision Race Components (PRC) cylinder heads come fully CNC-ported and machined using state-of-the-art technology!
PRC's aftermarket casting LS3/L92/L99 cylinder heads come standard with the following options:
NEW PRC 13-Degree Valve Angle LS3 Castings
Improved Piston-to-Valve Clearance For Extra Compression & Larger Camshafts
Smaller Than Stock Intake Port Volume For Improved Port Velocity
Manley Stainless 2.165" Intake, 1.60" Exhaust Valves
Your Choice of Spring Kit
Completely Assembled and Milled to Your Specifications
60-68cc Chambers
All PRC cylinder heads are extensively researched and tested. The all-new PRC aftermarket casting LS3 cylinder heads are designed to flow like a ported casting while keeping the port sizes smaller for improved port velocity. The result is a cylinder head that is over 10cc's smaller than a stock GM LS3 port and moves more air than a ported GM casting! These heads show dyno-proven 40+HP gains over stock 6.2L cylinder heads! The flow data below shows the superior performance of the PRC LS3 and L92 cylinder heads!
The all new PRC aftermarket casting LS3 heads are the perfect option for stock cube LS3/L99 & L92 engines looking for the most powerful LS3-style cylinder heads that we offer. Engine dyno testing has shown big power gains across the entire RPM band compared to even the best ported stock GM castings that we have tested!
The 13-degree valve angle will allow for the ability to run more compression and larger camshafts thanks to an additional .040" better piston-to-valve clearance!!

I can't wait to get this short block done! I will be using these heads under some decent boost on a 364 ci motor. We will see what it can do.
I will be calling TSP for some main studs. Everybody is on back order for them, Summit and Jegs.

I'm on the fence until I see dyno numbers but the smaller intake runners sure makes more sense for more power over the entire power band. I'm ready to pull the trigger and these soon.
Good luck with Dyno!!!!!

since they are aftermarket castings were the deck plates made thicker for higher horsepower apps? I see they are six bolt so im sure they would be.
My head was set on afr's 225's or something like that but these are 400 bucks cheaper and i could just convert to ls3 heads for that price.
Also, by chance could i order a set without springs? I have two sets of your prc springs already
