How to Measure and Set Up your Valve Springs for Best Performance. - Hot Rod Jay

Hot Rod Jay breaks down how to accurately measure your valve springs for optimal performance in your engine.
*EDIT* During the measurement for the installed height, Jay accidentally transposed .083 with .038 in the calculation. Just a clarification.

Truly a very thorough look at the importance of getting the best measurements and how important it is. Done very nicely. I have a saved to copy for reference.

Great explaination and info!!! A lot of guys think that you just buy random parts in any order and bolt them on and expect everything to work properly and make big power. People need to understand how things have to be matched properly to achieve what they want out of their engine!!

By far .... The best video on valve spring hight I have ever seen!!!! Thanks

[trinidadcamarillo-gl]

Thank you! Best explanation on how heights relate to spring rate and spring selection and options. Great content!

Appreciate the tips and tricks I'm just now trying to get into redoing my own heads and I need it all of these tips I'm 🔒 in watching an learning 👀 🍿

Excellent video, Jay does a great job of explaining the "whos and Whys" and how to make changes to dial in the results needed for your application.

I’m currently setting up a 212 cc RACE HEMI for my Mini Bike. This Video is Knock Out ! THANKS…+*+*+*+🙏💪🙌💕👍😎

I don't know if already mentioned, but having a "little extra" seat and open pressure on a hyd roller allows for wiggle room when the valve springs become fatigued over time/use. So the engine/cam/valvetrain will be less likely to experience valve float as the engine gets up there in mileage. Not too much extra to increase unneeded stress, but a little bit is not a bad thing.

This jay guy should be teaching this in a auto class in high school or in a college.. he is very thorough an very attention to detail an great math skills an totally understands his stuff an is triple A at explaining .. very very good video very informative.. this helped me Learn about this I’ve always wanted someone to teach me so I can understand this an he jus did it for me .. an at no better time than now as I’m actually going through this process on my truck right now .. I’m so glad I found this channel an video .. thanks for sharing 👍👍👍👍🏆🏆🏆🏆

Excellent video. I would absolutely change the springs. Im currently in this very situation with my Edelbrock heads.
Mine have hydraulic flat tappet spring from the factory. Spring pressures are way too high for the Howards cam im installing. Howards tech gave me the spring kit that will put me about perfect for both seat and open.
A bit of an expense, but worth it in my opinion.

Thanks for vid...a lot of useful info 👍

Great video... I'm thinking about the Edelbrock rpm heads for my 5.0 in your opinion are they worth the money quality wise and what else should I do to them to improve them if at all possible...

[rokhedjo]

I would love to know about that tension gauge set up you are using 😎

[coleenteabo]

Great video guys! I always thought it was best to buy the preassembled heads🤔👍👍👍👍👍

Hi good job and video so do you have a set heads for 302 ford mustang

[raymattox]

I realize this is an old video, but every time I watch it I want to ask you about your calculations for the open spring pressure. Your calculation should have been 1.995 minus.530 = 1.465. For some reason you used 1.948-.530 = 1.418. This caused you to check your open pressure with .047 too much lift, in other words that is why your open pressure was so far off from what you expected it to be. Right? 31:36

[dosher]

That is why you order your springs and lifters with your cam.

[Supanova]

Do i need locators on a sbc steel head? or just shim it to the installed valve height?

[craigfiles]

Do you add the rocker ratio into the lift calculation as that would be more than 317 pounds

Is CC'ing some kind of shorthand for measuring volume in CC"s?
Why are we measuring this area in metric units for a 350 cubic inch engine?
