rocker arm question

[extreme gmc]

crane part # CRN-10751-12
will this work on a 03 4.3 without the rocker arm conversion. to make life easier on you guys, let me ask this. does the 03's have a 3/8 rocker stud?
thanx!!!

our engines don't have studs. in99' they put roller truniuns in and they use bolts that get torqued down to a specific amount. their not adjustable. to make those work you need the conversion studs and taller valve covers (mine are for 88-93) they work perfectly but you have to cut the dividers out.. if you don't want to use studs slp make a 1.6 rocker set that are not adjustable and not roller tip for $400. but you wouldn't have to modify anything then.

would taller valve covers fit under the a/c compressor?

so what all would i need to make those work?

yea the ones i got do. got mine off ebay for $25.00 new. their not much taller. just enough to clear the studs. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7977035113&category=33627&sspagename=WDVW. these are the exact ones i have only 20 bucks more.

ok, so i am going to need those valve covers. what about conversion studs and if so
where can i get the conversion studs?

[nomaboy]

you will need to devise a way to put your oil fill cap on.. i just used a piece of rubber tube and put it in the valve cover hole then i cut my old oil fill tube off of the old valve cover and clamped it onto the new rubber hose. you will need to make a gasket out of rtv or somthin and that is it. they fit perfect.

you can get the studs at summitracing.com.

how much taller are those purty chrome valve covers compared to the factory plastic?

sorry, just gotta get 700 posts
woo hoo!

maybe 1/4 to 1/2 inch. i think the big difference is that the crome ones are more square. the stock ones are tapered and that cuts down on clearance.
