What valve springs
Hey guys,
I have a 350 tpi, fully forged bottom end, Home ported and gasket matched 083, lt4 hot cam, and stock rockers
I bought the lt4 hot cam valve springs, but they wont fit in the heads.
What valve springs do I need for this cam?
Where is the cheapest place to get a new chip burnt for my car?

Re: What valve springs
You don't state what size spring ( dia ) you need to clear
Hot cam with 1.5 rockers is .495 lift so you need a spring that will fit your heads that has similar spec
to the hot cam spring
Min specs
.500 lift
100lb on the seat
330 lb spring rate

Re: What valve springs
I used "Z-28" springs in my recent build and they appear to be OK.
