MIght be time to get with someone more qualified than a customer service rep.
343# isn't that much with a 1.4" spring.

 

Does the Alex's spring kit business have a customer service to help with choices or the installation? I've only been on the site looking at kits to replace stock springs on one GT40P head. I would expect them to have better priced spring kits, and better choices than the big brands(for popular common heads).

 

I contacted Comp Cams. They said,
"Yes, valve springs kit part# GT40CS-KIT will work great with the b303 cam specs. "
Then I asked for installation instruction and they said,

"Valve spring kit part# GT40CS-KIT is a drop in valve spring kit for the ford gt40 heads. No machine work is required when used on a gt40 head. We do not have instructions for this kit because it is a valve spring drop in kit and install is straightforward. "

I have no clue on how to do it? Lash ? Valve spring pressure etc..
Any help would be great!
Thanks!

 

I'd be looking at alexsparts. There is a number to call on their site. I called with questions about my springs before buying them and they were able to answer my questions and made suggestions.

 

Thanks for the info!
