Alloy crossflow head? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Just in the process of building a 250 crossflow for a street stock.
my question is, is there one alloy head better then another? i mean has one model got bigger valves/smaller combustion camber then another etc.
Only meant to run a standard head in street stock so i was hoping to get the best head from the factory if there is one.

Hi, The 86-87 Ulp Head Is The Best That I Have Tried. Some Say The 200 Cu Leaded Head Is Better But I Found That Detonation Was A Problem.
I Am Building A Street Stock Aswell And Am Using The 250 86-87 Head. Just Machine Off The Sharp Point Inbetween The Valves On The Head Face. Also Check Out The Crow 1550s Cam. This Was Produced For Speedway. I Tried On In A Street Motor And It Was Very Good.
Good Luck..

hey
e2 head is the best stock head.
use ea outer springs and get some good retainers and collets otherwise you can break them.
and make sure your putting about 120kw at the treads otherwise your underpowerd.
i ran streetys for while found the wade cams where better then crows.
and make sure you have really good suspsion as well will make up for a lotta hp
what cars you running?

i thoght in street stock no porting is alowed.. so the E2 head would be the choice of the bunch. most street stockies can get 200-210 hp.. This is alot considering they still run factory carbs intakes and exhaust manifolds...

ITs all in the cam

E2 head? not really into fords what model is this from? and how to identify it?
As far as I know no porting is allowed at all. and I will be running a ed falcon.
do any of you guys know a site with all the ford head specs? valve sizes,chamber cc's, etc

250 in an ED?????
why not the 4.0??

if you did mean the OHC 4.0, then I would have thought the newer the better?? non - VCT AU??

at the moment the rules do not allow fuel injection, so best to use 250 crossflow

hey
ive been told you will be able to run the 4inj soon?
the e2 head is easyly identified by where the front lifting hook goes or between number 1 and 2 intake ports there will be a cast number or letter from c1 c2 d e1 e2 f nothing there indicates its a leaded head.
no info like that on net mate but e2 i think is the only kit you can use with the acl raceseries rebuild hit and pistons from memory.
umm for inlet manifold get a 84da part number and exhaust i cant rember.
for the ed you'll have troble with exhaust clearance around the power steering and have to have custom powersteer lines made up much longer.
try and get a l/h clutch fork bellhousing so you dont burn clutch cables.
i use to run a 4speed in 3rd with a 4.1 diff spining the engine to around 5500 but really needed a second diff with a 3.89 or 3.7 for places like warrnabol where i ran out of legs.
oh and use atf gearbox oil in your diff and gearbox you'll pick up around 5rwkw
what you looking to run for suspsion?
