I am betting they will have simular numbers as MASTs heads.

 

Please post as many pics as possible

 

Will do...

 

whats the order to delivery time looking like ?
im considering switching from mast med bore LS3 to these..
i ordered the mast heads in November and still have not received them and i need my car complete and up to snuff sooner rather then later

 

I just mentioned that in a recent post.

Took about a month from the time I ordered to the time of delivery. Mine will be here Thursday.

 

Massive disappointment today......I guess I should have read this thread. It appeared to me from the way the website is that these are in stock, should have known better. I'm moving out of state in a few weeks and have a very small window to work with.

Wanted to throw a set on my truck to go with my cam specifically because of the small runners, but will now have to settle for ported factory heads. I bet these would be great for trucks.

 

Just got them today one day sooner than I expected. If the weather continues I may have some numbers this month.

PICS

 

Sweet, engine ****.

 

TSP, When are the PRC LS3 big bore heads going to be released????

 

Was wondering if anyone could tell me if these heads use bronze valve guides or powdered metal because I just remembered that I reused the stock rockers.

 

Itching to see some numbers on a stock cube ls3

 

I'll have the numbers very very soon...car is being built as we speak. I'll have dyno sheet and vids.

Might be done tomorrow...but I would guess Friday.

 

You can see the bronze guides in the pictures.

 

Also wondering this??????????? Need these BADDDDDDD!

 

Got results. Check sig and made a new thread.

 

Sorry guys, got no dyno numbers. Installed these heads on my LS2 Corvette, that was previously equipped with LS3 heads. Other specs:
Kooks headers, G6XE cam, FAST102, UD pulley, 4.10 gears. Stock mufflers. Idles, drives, sounds like stock. Due to traction issues at the track (no prep) I ha the same speed at 660' 97,19 mph as before, at 1320' I had 123-123,5 mph before, once I got 124. Now all the runs were 126, 126,7 being the best. The car feels wicked fast, I think there's an easy 128-129 in there with decent traction. Not bad for a stock behaving LS2 with a tiny cam.

 

I ordered 3 sets until now all of them took less than a month to get to me all the way around the world..

Made 492rwhp 468rwtq LS3 on Lumina SS (GTO) crappy 1.3/4 headers ORX , stock intake and tb , Big tires , 3.73 gears , G6X3 .
I'm very sure with a better set of headers , Fast intake the car will be over 520rwhp

The other two sets we still didnt install them yet ..

Great work like always TSP.

 

Great to hear^^^^

 

I had the same problem but with my stroker kit. Web site made it seem like they would be there in 3 to 5 days which was obviously not the case. They should list the wait times accordingly as it is not fair to customers on a schedule.

 

Yep,they are. I tried to bolt on a set of $1800 Jesels up today and found out the bolt holes are in different locations now. Great. Now I guess I have to buy some stockers or Yella Terras to get it on the road.
