Does anyone have any dyno numbers or quarter mile times with them? Before/after numbers etc? The PRC's seem to be really popular and really cheap. Also, was wondering how they affect daily driving and idle. Are there any heads out there that are significantly better w/this cam?

I agree

Wouldn't be a "bad" head for that cam. They will only help daily driving. With more compression your car will also idle better.

TTT for you.

Heads will make a cam seem much more "friendly" to drive than before, due to adding compression (read: torque) and typically having much better flow in the midrange. It will not effect the idle in a negative way at all.

I think the PRC 5.3l head would work great with that combo! At near 220cc runner & a chamber size from 62cc to about 58cc that thing should pickup about 45-50rwhp!

They flow
.300 206
.400 256
.500 291
.600 311

I think you'll find they work really well!! We had a 228cam car with these heads make 430rwhp through cats & stock vette mufflers!

Brian, I'd love to hear what you think it'd do with an a4 and a 224 cam!

FWIW, I have a TR224 on 114 with Patriot Performance 243 heads and I put down 401hp/392tq to the ground on a Mustang dyno. I have a pulley, but an LS1 intake, cats and stock Throttle Body. You could probably expect very similiar results. The tune helps a lot too by the way. Make sure to find a good tuner.

Which head is better? The 243's or the 5.3l's. Are you suggesting the 5.3's just to add compression without loosing p/v clearance? Does one head flow better than the other? I too have the TR224 and will be in the head market at the first of the year and was considering PRC or Patriot. I kinda wished I didn't live in Texas cuz I'll end up eating tax and shipping!

Just checked out yalls site. Is this the head you're talking about 199-PRC1.5
? How long is this price good for?

Check out my sig. Those times are will 411s gear were i was running out of gear at the end of the track. With some 373 i could have been mid 11s on motor and mid 10s on spray. Great combo especially for a daily driver.

do you have a relative in another state? have them pay for it but then ship to your house.

Nah, not a bad idea though

I think you'll find the PRC heads out perform the competition by a pretty healthy margin. When you get some extra time just look through the dyno section. I think you'll find PRC heads provide bigger horsepower & more consistant results compared to similar priced cylinder heads...

What cam would work best with your 243 ls-6 heads(with ls6intake,lg-pros.)?What are the runner size of the ls-6 heads?

I wasn't asking for a comparison between the two companies. I guess that came out wrong in my initial post. I was just making it known that I was looking at both. The actual question was about PRC's heads 243/5.3's.

Thanks Larry

I have personally never ran a PRC head. I have ran several different sets of Patriot heads (on my personal car now), and have always had good results with them. One particular car I have done was a 224/patriot 2.5 ls1 head with 59cc chambers. This car is absolutely amazing with its all around power and driveability. Haven't got it to the track yet, but dynoed at 428 to the wheels through a full catback (also m6) on a baseline tune. I have since put the car in speed density, and have added several other items. I'm not sure if the patriots outperform the PRC's, but they are similiar heads that run a couple hundred dollars cheaper per set.
