Lightbulb Heads and Intake Manifold? (Gurus needed!)

I was wondering how much RW HP/TRQ I would run
with heads and the Ford Intake Manifold with my mods.

Right now I am at about 315 RWHP.

I was also wondering if I were to go this route would it be better
to buy the Ford Racing heads... part # M-6050-463VP3, or just
get my heads ported?
How much does it cost to get the heads ported?

Also... is this easier on the engine and safer than going SC?
I really don't wanna hear the cost/value argument though.

Also wondering what the install price would be around for
having the heads put in and intake manifold as well.

Something I may do this summer.
Thanks!

The FRPP heads are expensive but they are IMHO the best, new castings and built with OEM strength equip. Livernois even thought they flow as well and are about $1,000 cheaper for pair they're made from used castings which I'm not a fan of on aluminum. As for the FRPP manifold I'd scrap that idea and put that $550 towards a set of cams that. The FRPP manifold will do nothing for you, it's most effective for turbo or centri style blowers.

you know you want to get the FRPP top end kit

Honestly, I think it would be a great addition to your NA set up, along with under drive pullies you'd have a great running GT. Sell the hot rod cams off of that kit, since you already have them.

Your gains will depend on what heads you get, what springs you have, what octane you run and how good your tuner is.

25-50 rwhp.

I would like to heads/cams and LTs and make another 80 rwhp with the same pulley.

I've already got cams! I have the Hot Rod cams.
You don't think the intake manifold will help with heads and cams?

What do you mean? I've already got cams and LTs.....
Same to Sparta... why are you saying for me to get cams?
I've already got Hot Rod cams....

So you're saying the heads and intake would only give me
25-50 hp with all the mods I have right now?

They are saying to go with a more aggresive cam since you are replacing the heads. It makes since to get a cam that can flow more air with heads that flow more air.

+1 on scrapping the FRPP intake manifold. You will lose a lot of low end torque to gain only a few horses up top. Drivability would go downhill and you would over-worry about the intake manifold having the "black lung" problem (we all know you would worry about it! ).

Hahaha holy **** I swear I need to have my title changed to
the paranoid one or something.
You guys know me well don't you?

Hrm... I just got these cams not too long ago.
Plus I don't buy the stories of the Comp Cams etc being better.
I gained 40RWHP with these and long tubes which is what you see
on those cams anyways.

If I were to go with a more aggressive cam.... if I wanted more gains
then what I have with these... I'd have to go with a pretty damn aggressive cam.
Wouldn't that hinder the daily driveability?

Also... you guys never said whether I should go with new heads or
just have a shop port mine?
The FRRP heads run about 2k correct? Would I get the same
results out of getting mine ported for less money?

The only way I would consider getting new cams
is if I could find ones that were really aggressive but would
still maintain street everyday driveability. Especially with me gaining 40 off
of these with the long tubes and x pipe.

correct me if I'm wrong but won't aggressive cams+ those heads cause a loss of low end anyways? why worry about the FRPP intake low down low when the top end combo will already yield a greater loss? (surely you'll gain a nice top end, 7k+ rpm)...

I am not sure if heads cause much low end loss or not.
I admit I'm not that savy on the tech on heads.

Smoke I was going to go the same route as you but I did the math and for the money spent in this N/A setup its cheaper getting a vortech supercharger. I was looking at Livernois Stage 2 heads which is 2099 plus 85.00 shipping, then VSR Cams, Springs, retainers, phaser limiters, hardware for the heads, head gaskets, and now your up too $ 3800.00. I see you have an aftermarket clutch thats good, plus I don't know how handy you are installing this stuff but if you need someone to install this stuff your looking at 1700.00 for labor now your at $ 5,500.00 and your doing this all for 380rwhp. Go with the vortech supercharger and get 450-475 rwhp. I mean do what you want buddy but remember building your heads is a crap load of money for an additional 65 rwhp. Brenspeed can install your supercharger for $650.00 oppose to your head build for 1700.00.
