I was considering getting some PRC Stage 1.0 LS6 CNC Ported Heads from Texas speed. I was just trying to figure out how much this is going to cost. Can anyone throw a quick list together on what supporting mods I need. I am also planning on getting an Ls7 clutch since I am still on the stock clutch and 10 bolt. So I am trying to figure out which to do first. Any input would be helpful.


Mods
Tsp 228R cam
Pacesetter long tube headers
Tsp off road y pipe
Slp lm1 cat-back
Ls6 intake
Ported tb
Slp lid w/ k&n
Ls2 timing chain
Ported oil pump
Prc dual valve springs
Tsp 7.4 push rods
Emissions systems deleted
160 t stat
Ngk plugs
Slowhawk tuned

 

Can't go wrong with those heads...that cam will appreciate the heads

 

Okay. I would also need to upgrade the lifters, and injectors correct?

 

I'd go ahead and change the lifters and trays since the heads are off; unless the engine has low mileage, but I'd still inspect the lifters.

 

It has 35k on it. So its pretty low for a 98 car.

 

Unless you're clutch is having any issues, might as well get a much as possible out of it. I'd go with the heads, lifters, and trays just for piece of mind. Your injectors should be ok. IMO those heads are the best heads for the money.

 

I know when I had a very similar set up a few years ago TSP suggested i get PRC Stage 2.5 5.3L CNC Ported Heads, it works very well with a 228R cam, stock injectors were fine but if you have the cash why not.

 

look at TSP head/cam install kit,bolts & gaskets.

 

okay cool. hoping for around 410 on a mustang dyno

 

So the ported ls6 heads should be good for 35-40 hp? Which other heads would gain more? Any input

 

go for the heads!

 

Probably looking at a number closer to 25hp for the gain, realistically, unless you're wanting to mill. Trickflow or Mast heads are going to be the way to go if you want closer to 40hp. You're looking at a little more than double on the price though.

 

really only 25hp?

 

What heads did you have before?? The 806 heads?

 

yes i currently have the 806 heads

 

OP I gained 38rwhp and 30rwtq from the PRC 2.5 5.3 heads. Milled to 61cc using GM stock thickness head gaskets. I was using the 224R cam that TSP sells.

 

ya i would expect around there

 

def get the heads. id wait for a bit though and go ahead and get a nice set and just do it once. small chambers and then as your setup changes pull em and have them cnc'd. injectors and heads are similar. you only want to do them once if you have too. thick decks provide quite a bit of insurance. if all you want is 410...then stick with the stg 1 for sure.
