Yes you can, but you can run into coil bind which is a bad thing
if shimmed to much. Shimming will help stiffen the spring, but is just a band aid for a flesh wound (or at least a real nasty ant bite
)

What he is saying...
If you add too much shim when the spring compresses it will not allow the valve to fully open and this will cause poor performance or catastrophic damage. I will be replacing mine when I get my injectors.

That was my friend after running a very impressive DYNO run, then doing a very unimpressive burnout in the parking lot. He lofted a hefty 546/998 on the dyno. The proceeded to do a lock-up burnout and dropped the valve at about 3200rpm. It went snap...pop...squeeeeeeellllll....and began belching white crap out the tail. #5 intake dropped, flew up and got jammed in the exhaust valve. The sound of a baby screaming isn't half as bad as this sound. Therefore, I will be putting F1 Springs in with my injectors.

That would be a flesh wound then

I do feel springs are a good addition.. The cam and head porting haven't exactly prooved themself to make a large difference in the diesel world. Atleast not in drag racing. In theory it seems great, though it just doesn't work that way. Even the "expensive stuff" isn't always the best for our combinations. SSminnow, W1ckeds' combination was properly installed and made less power. He pushes the limits with his truck. He's been through several engines seeking more power with his single turbo truck. For his combination, the stock cam and head have worked best for him.. This is also the opinion of Jeff Garmon, who tells everyone to go with a stock cam. Before you say "there's no way" again, theory and some vendors comments don't always make more power with our trucks..

OK, then it was poorly designed. You can keep trying to talk yourself into it, but you are not going to do it to me. Did not want to do this but I guess I have to, so...... I have been doing this a long time, and been around it even longer (my dad was part of a Pro Stock crew in the late 70's that went rounds with Bob Glidden and Warren Johnson and I got to hang around). I did my first cylinder head swap when I was 14, built my first motor when I was 16, I have built motors that have held MPH records in Fun Ford Weekend classes, and I just sold off my Pro Mod Firebird, 632" BBC that has been a best of 7.00's @ 205 MPH, my late model Mustang that has been 8.90's on motor, SBF, on a 28-10.5. I know what I am talking about. I will say it again, if you improve airflow, volume or velocity, you are going to make more power.
See if I can post some pics of some motors I have built:
This should be the 392 SBF that went 5.80's @ 120 on motor
This is the 418" SBF in my car that went 8.90's (I also made the motor plate)

CReed and Ssminnow
WOW! Sorry for insulting your intelligence! You guys (people on this forum) just kept ranting like air alone is just superior. I am sorry I don’t know every fact about people’s trucks you talk about. Next time before I post I will consult with you guys so I don’t put anything that might question your wits. After all, you had a 7 second pro mod car….I’m guessing it was nitrous as well…

Changing the subject a little bit here,but who was your Dad spinning wrenches for back in the day.Maybe I ran across him.I was around quite a bit then.Started out in early 60s at Masters Field in Miami,Fl and then National Trails right outside of Columbus,Riverside in Cincy,IRP and so on.That's back when the pro stockers were called F/X cars.I ran mostly blown 392 Hemi's and then got into B/MP BBCs,Then back in Mother Mopars S/S max wedges,and a few S/S Hemi's.
Don't mean to hi-jack the thread,so I'll throw this in and make it look good.Air flow is really good and the more air you got the more ponies you gonna put out,"UP" to a certain point then you have to add fuel to the mix or you will lean out and burn the house down.Of course everyone knows that and I still can't find my spark plugs.
