As the title says, which heads are you f13/14 guys using? How's the clearance? What kind of numbers are you seeing?

 

Patriot's stage II 5.3s. F13 cam. Bolt on and go! 422RWHP/400RWTQ. 11.14@120mph.

 

Pretty Impressive, Maybe mine will put down #'s close to that. Are you running a A4 or M6?

Im running Patriot Stage II LS6's with F13, no track #'s or dyno #'s yet though.

 

Your time looks good, but your dyno seems a little lackluster. There are cam only guys doing these numbers. Was this a mustang dyno by chance? Not that it really matters since the real proof is in your timeslip.

 

Could be an A4 also.

 

From testing we've seen a good cylinder head should pickup about 35-40rwhp. The last dyno testing we did resulted in a 39rwhp gain with the latest PRC port. Keep your eyes open for alot more dyno results coming soon, we're finally getting caught up on backorders Each PRC cylinder head spends 8 hours on the cnc machine, then 5-6 hours of additional finishing, extra porting & hand finishing before they ship! Alot of the cylinder heads go onto the flowbench 3-4 times for extra tweaking before they ship!!

 

That would make sense, but it says "Spec 2" and "Pro 5.0" in his sig...

 

Not in Charles Cyrus's sig it doesnt. He's the one that posted up his results. His sig is blank.

 

I stand corrected. DOH!!!

 

I love it,

 

Not a mustang dyno.The dyno numbers are with a M6, the car went 11.40s. I put in a th-350 and a 3800 stall and went 11.14@120 in very good air. The car weights 3275 pounds and pulls mid to high 1.50s 60fts on 28x11.5x15 et streets.

 

FM13 with AS 5.3 stg2 heads at 11.2/1 compression with a 90/90 Fast intake. 435/405. These heads are a 2.02 intake, no clearance issues. Was advised that the valve size is a big issue with clearance.

 

Although its not one of the cams you listed, I have the F11 with Absolute Speed Stage II - 452rwhp/413tq through 4.10's.

My roomate (Winman) has the F11 and Patriot Stage II heads, he's doing 439rwhp if I remember correctly.

 

just installed my f14 heads are absolutespeed 2.5 5.3's with a 2.055 valve ground down to 2.04 heads are not milled i had no ptv problems but i do use comp r lifters dont know if that makes a difference with my tight valve lash spec or not?
ill have dyno numbers in about a week ill post them than.

 

Anybody out there with some AFR205s/F14, or TEA stg 1.5 5.3/F14 setup? That is what I am looking into when the time comes.

 

someone on here has that set-up ill search later to see if i can find em for ya

 

Thanks man
