Im looking for info on the stock cvo heads. Im trying to figure out what size valve springs for max cam lift. Thanks!

 

They are SE springs and have ~175# seat pressure. They coil bind at or near .650 lift. I change them when going over .600 lift and use premium springs with Titanium retainers from Wood Performance along with Baisley rockers and geometry corrections.

 

Thanks deweysheads! I want to run Woods TW8-6 and didnt know if a spring change was necessary.

 

I might not know what I'm talking about, and usually don't, but I thought that the heads came with springs that only went to .575 lift? If you wanted more you had to purchase the SE race springs that sound a lot like what Dewey is talking about .650 lift. But like I said I could be wrong.

 

We are Bob Wood's largest account on planet earth.
His 160,188 and 200, psi springs are fantastic, and do come with a lifetime warranty and we do use them day in, day out, BUT, a Crane #1101 will work just fine also, in a less than .600" lift application.
We have all those, and Manley behives, on the shelf, 24/7.

Kinda like what Bob Woods has to say about his springs.

Never, never been a failure.---Right there--Works for me.

 

Bolt in in that motor

 

Got sidetracked there.
DeweysHeads straightened things out.
Warpig asking about his particular setup.
His SE heads should have no problem with the TW8-6.
