1.7 roller rockers ?
i searched the forum about the roller rockers but couldnt find an answer. are they direct bolt on? do i need to replace the springs? what else will i need? sorry if i actual over looked the thread that explains this all. thanks in advance
Yes they are a direct replacement. You don't have to replace the springs but if you've got like 200k plus and constantly red line the truck it might not hurt cause they get tired after so long but they aren't required. When I get mine I'm not changing my springs.
awesome guys thanks. yea i got less than 20,000 miles on my springs but the way i drive it it may seem like 200,000 lol. i may or may not replace them just will have to see what they look like. thanks again yall
You didn't search very hard, this has been covered a hundred times. As long as you buy HS non-adjustables, they bolt right in.
30k is nothing, that's just throwing money away. With the stock rev limiter you cannot float the valves. Throwing stronger springs on the stock 2 piece valves is a very bad idea. There is absolutly nothing wrong with not replacing the springs. I suppose you also like to change your O2 sensor(s) every 3 oil changes too 
I beat on my engine every day, with boost and no rev limiter, it's doing just fine.
It is actually recommended before that. It used to say it on HS's website, but with the revamp, the text disapeared. It was recommended that over 30k to replace the springs. All of you who don't replace your springs with 1.7's are doing it half *** imho (but that is just my opinion, and we will leave it at that). You all say you have no problems, but how about the damage on the inside that you can't see? Google "valve float". It has also been recommend a time or two to swap to hardened push rods to help with deflection because of the removal of the guide plates. How many do that? In the OP's case, it doesn't sound like he will have a problem, but you won't catch me tossing 1.7's on any time soon. To each their own.

Looking at your sig you have a "PERFORMANCE BUILD 318 308-310HP" lol. If thats the case and true then you should know that you all ready have stiffer springs. You are not getting that much hp out of a 318 with stock springs with out boost and stock spring will not yeild that much hp N/A. Heck you can open the stockers with you hand there that weak no were near enough seat pressure for a higher lift cam. Next is pv clearance. What cam, pistons,heads,springs are you running?
