Headswap on the way. Need some help

[97GTSTANG]

I have a 97GT and i have started installing a set of 02PI Expedition Heads 5.4L. Well the heads are on and I am trying to install the timing chain cover and for some reason some of the old bolts are too small and they dont fit in the heads. I was wondering if someone can please help me out get the right size. I talked to Randy and he helped me out a lot. But I need more of the bolts (the two sided bolts). I guess other accessories attach to the other side.

I have attached a pic, but I have more if you would like to see.

THanks

any ideas?

Your old heads are 8mm the new bolts are 10mm. There is a kit you can buy from ford that has the right studs etc...PM 96mustangjames he just bought this kit maybe he has the part #. I just got some 10mm bolts to make mine work

 

[97GTSTANG]

Thanks. I will do that. I got some 10mm bolts but its a tight fit. I was told to get 10mm with 1.5pitch and 55mm in length. Is that what you got? Thats what i got and its a very tight fit, so hopefully it wont cause a problem.

 

[Jr2fast]

yeah but mine did not go through the brackets and all very well and I have a very small leak right there, not enough to cause any concern but still I need to fix it later

The two sided bolts (studs) are Ford p/n N808140-S309 and the standard Ford 10mm bolts for the swap are p/n N808142-S309. The studs come in a package of two and the bolts come in threes. I have two new studs and five new 10mm bolts left over from my swap, pm me if you need them.

hmmm....thats weird!! how do you explain me not having this problem?
Just curious because my original bolts all went right back into my new 01 heads??? am i missing something?

You would be the first I know off. My guess is mine are 2000 heads (windsor) yours are 01 (romeo)

that sounds like the only possibility? Must be they went back to the 10mm on the romeo heads?

 

[Jr2fast]

could be my 96 romeo's had 8mm though not sure about the 01-up romeo though

you and me both....I just finished up my headswap a few hours ago and I reused my stock studs. I have '01 heads BTW.

What power increase does one usually recieve by doing a head swap?

 

[Rio97GT]

There is a compression bump that gives a little extra because the 96-98 GT's have a smaller dish in their pistons, so around 50-60 hp.

glad to know im not the only one that got lucky.

if your referring to the 8 or 10mm bolts we are talking about then no, they do not come with the kit. atleast mine didnt that i ordered through my local ford dealership.

:damnit: i hope mine fit without the new ones then.

How do those 4.10s fel w/ the headswap? im thinking about going that route

 

[Fullthrottle!st]

Did they fit?

Did you have to replace the bolts. I'm about to put 2000 PI heads on a 98 GT. If so, were there any leaks?

Thx

I was told I would need all those 10mm bolts when I was doing My head swap (96 engine with 02 pi heads) Well i spent 25.00 on the stuff and never needed any of them All of my orginal stuff went right back were it came out of.
