Hey guys. I was given some vortec heads and was wondering if these valve springs I have below will work on these heads. Meaning can I just put them on the heads without machining the spring seats??? I seen on EBAY on Alex's Parts he sells a kit that have the same O.D. and he says the fit right on the heads with no machine work. Can I use the ones below????

Thanks Guys.

Valve Spring Info:

1.265'' Dia. Single H-11 Valve Springs,
Seat Load: 130lbs @ 1.700''
Open Load: 395lbs @ 1.150''
Coil Bind: 1.050''
Max Lift: .610''

your vortec heads have pressed in studs or did you put in screw in studs?

The problem is not the spring. its the inside diameter of the inner damper.
The spring choice does not deal with the retainer to seal/guide boss lift clearance with high lift cams.
You still need to shorten the guide boss. and or use special non stock retainers.

Ok guys thanks. Im just gonna buy that kit through Alex's Parts that gaurantee no machine work needs done to obtain .550 lift. I think that would probably be about the limit on lift numbers with vortecs any and that would be fine with me.

Thanks guys for the help

make sure the springs dont pull the studs out

I am going to get new studs but is there a way that I can get the pressed studs out myself. Also I have some 2.02 and 1.60 valves I am going to use. How much of a difference does those bigger valves have over 1.94 and 1.50 valves.

if you plan to get new rockers? turn a rocker upsidedown reistall the jam nut and washer with an impact gun until the studs pull out.
the 202 valves are not worth the effort to install in vortec heads

If you just install 2.02 valves without porting the flow goes down on a vortec head.

you must port it too to get a gain.

Ill stick with the stock valves. Thanks
