L92 Heads whats the difference in price
L92 Heads whats the difference in price Ok.. here is the question. I have a LQ4 Im building, I am looking at the L92 heads
These are from Scoggin-Dickey, 12582713 Scoggin-Dickey 798.50, Im using the car-craft article as reference http://www.carcraft.com/techarticles...ocker_arm.html
So they are 798.50, plus springs. Lets say they end up being 1100 for springs and heads shipped. I am also looking at the texas-speed set up, but is much higher priced. Whats the difference?? I AM!! building the car-craft set up, but if I can get some benefit from I will consider it?
Thanks in advance.

The difference is that the TSP heads are ported, and have aftermarket valve springs in them, which you'll need unless you plan on running a stock cam. They'll make a decent amount more power than the stock L92 heads from Scoggin-Dickey. By the time you buy an aftermarket valve spring kit for the stock L92's, from SD, it's going to end up costing you only a couple hundred less than the TSP heads, but they won't flow as well.
Why not just go to Scroggin Dickey's site and look up information instead of getting the wrong info on here.
GMPP heads stock and upgraded springs
SD's own CNC ported heads

Hmmm those L92 Heads flow pretty good out of the box. If I get the TSP heads, can I drop a bigger cam...and get benefit?? The HP that Car-craft came up with are pretty good.. Maybe someone from TSP and give me some insight?? Stock bottom end LQ4 with the carb set up
As stated, the PRC heads are fully CNC ported with a competition valve-job, your choice of valves, and the spring kit of your choice as well! When you price around the CNC work and all, the PRC heads are very competitively priced for the performance you gain versus a stock L92 head!

The intake flow on out of the box heads is good, but the exhaust flow is a bit on the low side. The CNC heads will pick up the exhaust flow making them a better overall head. Getting air in the cylinder quickly doesn't do much good if you can't get it out efficiently.

Here is a good comparison, Edelbrock big block Chevy heads
http://www.edelbrock.com/automotive_...erf_rpm3.shtml
Edelbrock BBC 320 intake and 211 exhaust @ .600
L92/LS3 at about 320 intake and 208 exhaust @ .600
Not sure where its lacking either.
