Ported heads with stock cams in new 5.0?

[Badass2000GT]

Would there be any benefits doing this? I have long tubes, boss 302 intake, off road x-pipe, magna flow cat back and CAI. Just curious what would the pros and cons be on doing this with stock cams.

These heads already have 110% volumetric efficiency. I would leave them alone, personally.

However, the Boss 302R head is CNC'd, but it only flows 4% more.

M-6049-M50BR* RH
M-6050-M50BR* LH
• Fits 2011-2012 Mustang GT
• Production cylinder head used on the 440 hp 5.0L Mustang
• Loaded head assembly minus camshafts, rocker arms and lash adjusters
• 37 mm hollow stem intake valve
• 31.8 mm sodium-filled exhaust valve (31 mm on base 5.0L)
• Increased rate valve springs can support 12 mm intake and 13 mm exhaust max lift (base head is 12 mm/12 mm)
• Fully CNC’d ports and chambers
• Flows approximately 4% more than 5.0L 412 hp on intake side
• 193cc intake port volume
• Chamber volume nominally 55.6 cm3

For a max effort N/A motor, ported heads would be of some benefit in the upper RPM range (similar to the Boss intake gains), but for normal street driving, you'd never get anywhere near the revs to feel it. The stock cams are pretty good in these motors too, but there are some gains to swapping over to the Boss exhaust cams. The downside to that swap is I believe they are only compatible with the Boss heads.

No one else has any input on this subject?

If I'm ripping it apart to port heads, then I'm putting cams in there. There are a few options from Comp.

Here's what someone else did. Not sure what your goals are, sounds like you're thinking pretty serious.

I have recieved tons of emails and phonecalls about our car for awhile now and especially after setting the N/A stock longblock record a couple of weeks ago so I figured I would set the record straight and post up the specs on this car.

Awesome weather/DA/Tailwind, most likely wont repeat that run again anytime soon. We also went 10.97 that day with a 1.56 60ft.

I hope that clears up some of the questions I have been getting.

Thanks everyone,

I'm debating back and forth what I really want. But I've been thinking to see if you can get this new 5.0 to 500 plus rwhp N/A and be reliable. I know I should use that money towards an SC and be done with it but I'm just not a SC fan.

[46Tbird]

I kinda doubt it. The highest I've seen was around 440rw and it was a pretty serious build. Maybe heads and cams would get you there all motor, but like I said - I doubt it. Since the Shelby is getting a 5.8 for 2013, I'd expect one to show up in a GT or Boss in a couple of years and that might be able to crack 500rw NA.

Tuesday I'm going to gearheads to get my car tuned again since I added long tubes and boss 302 intake. But before the headers and the intake I made 422 rwhp. So maybe I'll be at 440 rhwp. As of right now I'm not going for that goal cause I don't see spending 1700 plus dollars just on cams. So hopefully in the next couple of years they will come down in price.

Could always just throw on a TVS or KB. My car picked up 200rwhp at 10psi with the KB2.8LC.

[Blackpony]

Diddent you just have the car tuned at hpp? Why go to gearheads now?

They gave me one hell of a deal on long tubes and boss 302 intake and tune. I got a price quote from HPP and Gearheads was A LOT cheaper.

I said this earlier Dave.

500 hp is totally doable. Just drop your car off in Maryland with Justin Burcham and tell him you want the Top Dog package

Yeah I think I get my stuff local. But it is good to see that it is possible.

I like to stay local too for the big things, but JPC is pretty much universally recognized as one of the leaders in new 5.0 tech. I just wonder how much fun it would be as a daily driver? Hell, you can blow $5500 on a new Vortech kit and have over 500 at the wheels and it'll drive like a stocker. Can't help but think that Top Dog package would be a little "high strung".
