I know there are 3000 of these threads but each one is a little different.

My goal is to make my engine as reliable as possible and while i'm at it gain some additional performance.

My car is an 06 with 35k all stock.

I'm looking at

PRC 165 heads
Torquer 110 cam
headers probably kooks with catted x

So what parts will i need to do this - what length pushrods and what other parts do I need to complete the install?

I might even want a more mild cam. how driveable is this cam below 2000 rpms when cruising in traffic?

Keeping the stock intake setup (i don't have a large budget... wait i don't really have a budget).

Any advice on this is appreciated. I was hoping to do an event on March 9th and just pray it doesn't grenade but now I'm having second thoughts and just want to get this done before going back to any track time.

Well at least your doing something proactive. I know about the Texas Speed PRC 265 heads and have heard good things about the Katech 110 cam and Kooks headers. The most important thing is to get those heads replaced. Drive the car like you have an egg under the gas pedal until you get these mods done. It's your car but I wouldn't even think of tracking it until this work is done, unless you have an extra 15 grand laying around. Keep us posted.

Yes I will.

I woke up this morning and decided I'm going to ONLY do the PRC heads. My oil reports show 3x high iron which obviously points to valve guides - UNLESS it's came lobe/lifter wear (which I've seen a few others with soft cams pitting). Need moar monies

That's great. While it's apart you can have the lifters looked at. I was surprised at my cylinders when I removed my heads. I have 69k miles on the car and there was no ring ridge whatsoever. They all looked like new bores and I could still see hone marks. These motors could last 300k miles if you take care of it.

My car is finishing up at ECS today ('10 Z06). After much research and planning, went with: Torquer 110, WCCH Brodix LS7 style heads, Caddy high speed lifters, Che rockers, new radiator to get much needed better cooling and oil cooler (also heats oil faster in winter), new twin disk clutch, etc.

Will be putting results in a new post sometime in the next day or two - no headers for now...

Pros and Cons between PRC 265 & 285?

Know that later on I will want to add a cam, headers and intake. For now I want to get my car safe before March 9th event.

Will I be ok just throwing the heads on, no tune? Won't hurt anything right?

Can I use stock lifters with the PRC heads? That is, if they check out ok. I'm gonna go ahead and rip my heads off this weekend. Well, if we don't get any fresh powder that is

erichg1000

And damn. The demand for these heads must be through the roof. I swear the base price was listed at $2k a couple days ago. it's now at $2.4k

DOUG @ ECS

All ready for pick up!

You want a great product with awesome results at a great price, contact Darin Morgan. I am so pleased with my car.

I decided to do my heads a couple of weeks ago, then it spiralled into rebuilding my stock heads, custom cam, kooks LTs and porting the intake/tb. and an HP Tuner pro on top. Careful... it does tend to snowball on you.

If you are going to run a small/mild cam i say do the PRC 265 But if you're going to do a large cam go with the PRC285 to get the most out of the cam.

I have an LG7XX Cam i belive its the largest of the LS7 LG cam series. It surges a bit in the low RPM though but it dosent bother me it sounds amazing at idle and Pulls great through the RPMs. When i come back from afganastan im going to get the PRC285 and sell my stock heads. my goal is to be at 600whp + or - 10 on motor.

This is a walk around of my Z06 with the 7XX Cam.


MERICA!

So if I JUST do the PRC 265 heads for now - will my car perform even worse than stock until i get a cam/tune?

The heads should be just fine without a tune. You should get a small boost in torque through the power band but it won't be a lot. You might get as much as 10 horsepower peak but not much more.

X2!

Excellent suggestion Nacho.

I have Darin Morgan heads and my cam is by Mike Jones.

I recommend both very much.

Since your NOT changing the intake to take advantage of the PRC addl flow rate, then why not just send 'your' own heads and have them reworked.....much less moo-la doing it that way. Have them do some extra work on your heads, and then when your ready to spend more moo-la they will be waiting (already re-installed on your ride) for your next folly to begin.

C6 Curtis

^ Its about the same price after you sell your stock heads. PRC also has a $900 exchange plan for the 265's

RedZ4me

no...been watching for months, been $2399 for some time now plus options. 265's are what you want. Mine will be $3000 with ti intake, ss exhaust.

JwT

These heads have been this price since last October and have small advantages over stocks. First the rocker geometry is correct, second they have a much thicker deck so if you ever want to boost their safer. Remember why your installing heads in the first place. The object is to loose the exhaust valves as soon as possible. Doing nothing may put you in the (Another Dropped Valve) section of this forum. In talking with the guys at Texas Speed the 285 heads are for engines that are really worked. You can actually lose hp going with the larger intake runners. I installed the 265's and was told I would gain maybe 15 hp but only at the top end.

C6 Curtis

That why i said if you have a big cam and supporting mods the 285 are better. prc 265 are good for a mild cam street setup.

You are correct. I was mistakenly looking at the PRC 265's that are for the small bore LS3.
