Whats the pros/cons of using stud mount rockers and ped. mount rockers? I need a set for my heads, and want to know which would be better?

Studs are stronger and easier to adjust the lash on. Ever tried adjusting lash on pedestal mounts? You gotta use shims, huge PITA. The only downside is the neccessity of guideplates, which then require hardened pushrods. But they are SO worth it if you are installing them yourself.

hey, i found some comp cams 3/8th stud 1.7's...but it says that you dont need guideplates...is this right?
what heads are you using these on? if your using em on the p's your gonna have to get them machined
p heads are setup for ped mount. a machine shop would have to machine down the pedastals and i think re-tap them to run stud mount
it's a real pita to machine the heads right. they have to take off some material on the mount pads, drill out the holes, and tap larger holes for the studs. taking of the material is to accomdate the increased install height of the guid plates and studs. if you don't plan on spinning your motor over 6k, save your money. just my .02
urban beat me too it, but do you really want to sink all that money into some P-heads. use your stock rockers, and save up for some nice alum heads with studs already in them.

Everybody try to remember this as it will help later on when you think about this subject. 
All Ford 5.0 OEM Iron Heads are set up for ped rr's.
Its a cheap way to turn em out and thats why Ford did it.
I have seen in the past, some kits to convert to stud mount but the whole deal was kinda Mickey Mouse as the stud was so tiny ... IIRC 5/16. Anyway, just not strong enough for a serious effort.
For iron heads, I still say this if you are gonna only be using them for a while
Don't buy new rr's for them cause they are gonna be peds and I can't see the sense in moving those rr's to a nice flowing Aluminum head when you go to the next level. Just use the stock rockers and don't take the hit in the wallet when you sell the iron heads. As for the gain from rr's ...... give me a break ..... 5 hp or less ...... Just don't make sense to me!
It would take a good bit of $$$ to do studs correctly on Ford OEM heads.
I'll never change my mind about sinking money into iron heads

grady, i will be keeping the iron heads for a long time...although i'm not going to put the money into them for stud mounts, i'll just get some 1.7's and be done with it. Thanks for the info

I said that once upon a time about a set of self poted E7's I now got just laying around in the garage
"and be done with it"
That was exactaly what I said when I was porting the E7's
Lets tell the truth about what we ALL want from our combos ...........
