Anyone runing Roush heads

JamesB88 · May 7, 2007

I have a chance to pick up a set for $600, they are machine shop fresh, have 2.05 and 1.90 valves in them. The are milled .015, trhey are port match to the cobra intake i already have (bought the intake from the same guy) The car has a E cam in it but thinking about building another motor for it. Anbody runing these cast iron heads? Really thinking about them just wondering now they perform. Also wondering if a E cam would be to small for it or i should go with a bigger cam. Thanks James.

IMO you couldn't go wrong with roush heads. $600 seems like a good deal

JamesB88 · May 10, 2007

Looks like these arent that popular of heads. Hopefully pick them up next week.

hah the price is usually too outrageous for roush anything. they make good stuff though. what do they flow do u know?

JamesB88 · May 11, 2007

Not sure about flow numbers, the have 200cc intake runners i think. THey are port matched to my Cobra intake i have the guy was going to put them on his car.

JamesB88 · May 13, 2007

Nobody? Wonder what size cam to run with them. Probly going to trade my mud truck for them.

You'll more than likely have piston to valve clearance issues with a 2.05 intake valve. They're an inline valve head, so you'll absolutely need to check clearance, but more than likely have to notch your pistons for them to work.

Hmm.. Think I would be better of buying a set of Trick flow or AFR heads?

EDIT: Talk to him about them and turned out they had 2.02 and 1.60 valves, should be no problems, right?

I have the windsor Jr heads, and just like most on the board here, feel the large valve and intake runners are too big for a modest 302. With an E or F cam, the enging really comes alive around 3000 rpm, but suffers greatly on the bottom end, regardless of cam size. So, If you want a drag car with a 2800 stall, .411 gears, they will perform well. If it is your daily driver, port some E7 or GT40 heads, or buy some AFR 165's for an additional 600.

JamesB88 · May 16, 2007

any idea what kind of power you make with them? Im going to have 3.73s with a 5spd.. think it would lack alot of bottom end, i also have 3" exhuast.

if you plan on going bigger later...then get those heads. if you plan on just doing a couple mods and keeping it relatively tame go with something like the aformensioned afr's. if you have a power adder on the horizon, do the roush heads def!

JamesB88 · May 16, 2007

Probly going to go with a blower after i stop daily driving it. Right now just runing N/a, but have a nitrous kit for it, thinking about a 100 shot.

JamesB88 · May 18, 2007

Well the motor blew up, its blowing by really bad, blowing the pvc valve out, has a pop every so often and is missing now. So quess ill get to build a new motor with the heads. Perfect timing huh, but to bad i dont have anything to drive.

91 HATCH · May 19, 2007

was it the nitrous that blew the motor up or what

JamesB88 · May 19, 2007

I was just driving it back to work, the car has 350k on the body, the motor has probly about 150 on it. Ive never spraied it, its got some old DV heads on it i think its got a valve sticking or something, but its also blowing by really bad. A TON of smoke comes out if you take the oil cap off when the car is runing a few mins it does it really bad, but its not smoking much out of the exhuast, it does alittle on start up. But it started missing really bad, and i changed the cap, rotor, and plug wires are maybe 2 month old FR 9mm wires, and it has plugs that are about 2 weeks old. I pulled them all off and the number 1 cylender didnt make a differnce when i pulled it off, i havent ran a compression test on it, just going to swap motors so i can rebuild the motor with the H/C/I. I used to deliver pizzas in the car so probly ruined the rings with all the sitting in traffic and runing for 5 hours straight. Im swaping the motor out of my vert into it, It runs pretty strong has 110k on it, going to run it while im rebuilding the motor that was in the car.

JamesB88 · May 26, 2007

PUt my verts stock motor in it, got the car driving again. Going to go threw the old motor and stick it back in. I found a set of Performer RPM heads, they are almumium do you think it would be better to run those instead of the roush ones?
