What are all the parts need to do a head swap? Do you need the cams from the PI head too? Just wondering what if takes for material to get the job done from start to finish. Thanks

what vehicle are you planning on the head swap. the 02's already have PI heads. The PI head swap is for the 96-98 4.6 SOHC. the 96-98 models had restrictive heads and the 99+ model years it was fixed. this is why the HP increase. also putting 99+ heads(PI heads) on a 96-98 will increase the compression so SC'ing will be out of the question.

Are the part different for the different years 96,97,98?? Let's just say a 97.

96-98(Romeo) have the same crappy heads........99-00 have one style PI Heads(Widsor) and 01-03 have a different style(Romeo)........the 99-00 take different style valve covers. So if you are putting a used set of heads on go with the later version. They are a pretty much a straight swap, there are other things you have to switch as well on the 99-00 style but I can't remember(I went with 02's with 3Kmiles)........You will have to go with a different intake as well(go with no later then 02 because they have to all aluminum crossover)........If you need anymore info I'm here and been through it.........

Can you use your stock cams or do you need PI cams? Cam Sprockets? Timing chain tensioners?

[mustangjeremy]

stock cams or do you need PI cams......I have heard they do interchange but I don't I wouldn't try it....... Cam Sprockets......they are the same......... Timing chain tensioners........same

It would be nice to use the PI cams, they are much better.

[mustangjeremy]

I actually read somewhere(I don't remember where) that you can put PI cams into non PI heads........Not sure if you can or not, anyone else here that...........

[driftpin]

So basically all you need are the PI heads and PI valve covers and most likely a set of PI cams and retainers. Are the lifters and rockers interchangable as well?

[mbhmustang1998]

mustangjeremy..yes u can put PI cams into non PI heads, i hear they are good for about 15 horsepower or so, dont know exctly tho, but there have been people i talked to on here that did that, i am thinking about just doing that for now, and maybe porting my heads with pi cams..or maybe just pi cams

[mustangjeremy]

I have my old set of heads and I can even port them for you if your interested............25K miles on them and look brand new..........

[mustangjeremy]
