Valve spring identification
Valve spring identification Hey, I found a good deal on a set of CNC'd 243 heads, but I'm not sure which valve springs are in them. The seller gave me this info that he got from the machine shop about the springs:
The open height was 1.237, binding at ~1.080 with clearance of ~ 0.160 and a rate of 385
If anyone knows what kind of springs those might be, that'd be great.
Or at the very least, I just need to know how much lift they'll handle. I'll be going with a TSP 228 cam most likely, which doesn't go over .588" lift.
Thanks.

Assuming they setup at 1.800" installed height (it'd be a good idea to check that), they'll be good for about .650" lift or so leaving .070" to coil bind.
