More Head questions...

Are these any good????

ford racing parts are usually quite good. the valve sizes look good to me, too.

but what engine are planning to put them on? you can retro-fit HO heads to a regular 302, but the main concern should be the compression ratio.

you could play around a little with the numbers here:

Here's a quote out of the '01 Ford Racing catalog:

GT CYLINDER HEAD ASSEMBLY
M-6049-M50
A new stock replacement cylinder head for 1987-95 5.0L Mustang GT or 1987-96 5.0L/5.8L trucks. These new head casings are assembled with new stock valves, springs, retainers, seals and valve keepers.
*1.78" intake valve, 1.48" exhaust valve, 65cc chamber

Sounds like they're equivalent to E7s with a little bigger combustion chamber.

 

It would cost me less than $100 difference to do a standard valve job on my E7s as what those heads would cost with shipping. Just didnt know if they were worth it. The car is going to be a cruiser although I am planning on putting a 331 stroker kit in it.

 

those heads are e7s...zoom in on the chamber pic, the e7te cast# right there....hey 400 bucks and everything is brand new..not bad

 

Are They Worth It??

Hi,

JEG's advertises a house brand pair of Ford SB aluminum heads with 58 cc combustion chambers, large valves, and 170 cc runners for $ 539.00. This is not exactly my cup of tea. I am going to use RHS heads with 220 cc runners. However, for the extra $ 139.00 over the Ford heads on E-Bay, I think it at least worth your time looking at the JEG's product. The weight savings is about 80 pounds over cast iron.. I expect the flow chart results would be far better too! I hope this is helpful.

AFR 165'S! Port the E7's or don't do the 331 its working against it's self. Id just do port work and bigger valves on the E7's and ride. But 165 AFR's would makes a nice engine.

 

You had my attention but I think that price is for ONE head.

 

Why would putting in a stroker kit be a disadvantage over stock rotating assemble regardless of which head I choose? I have to buy pistons and a crank anyway. More displacement makes sense to me, at least I thought it did.

 

Shipping both ways is still about half of what it would cost me to get them done here.

 

the biger you make the displacement of your motor the more air it takes in at any rpm. in effect you move your power band to lower rpms if you all you do is increase the displacement. to take adavantage of a stroker block you need to increace your air flow ablity. so puting stock heads on a 331 will not make more power. it will just give the same power at a lower rpm. the feeling will feel beter in the lower rpms where you cruise at. but your performance wont be signifacantly beter. for the price of those heads, if you put that money into having yours ported, biger valves and new springs put in. this will give you more bang for your buck.

 

Ok, I get that. Problem is around here it costs about $225 a head to do a stock refurbishing. Get into porting and larger valves and the price probably doubles. I could just buy a set of Edelbrock aluminum heads for $1K. I really wasn't looking to build something high performance. I got my Sprint to tickle that fancy. Just want something that cruises good and will pull a light trailer with little effort. But mostly good gas milage on pump gas. Yea, I know, the best of both worlds.

 

I just wouldnt spend any extra on the 331 kit if i couldnt use it. Kind of be like putting a one barrel carb on it. Not that its a bad thing, but im tight like that and it just wouldn't be efficient at all.

 

i got a set of e5's that i am told are the same as e7's that have around 2000 miles with 5 angle valve job,new seals and 20 thou shaved.need's valve springs for whatever cam your gonna run.they have been sitting since april.yours for 50 plus shipping.


if i were you and you dont want to spend a ton you could find a set of gt40 heads.they run better than e7's.

 

Dennis, I just listed these on Craigs. A lot of work went in to these, also these heads were on my motor when we ran in Manasass.
