Roller Springs for Speedmaster heads

[HuntedDuckV351]

PBR is porting a set of speedmaster heads that will have a .700ish lift roller. What roller spring are you guys running with these heads? Will have HS 1.6 rockers with B3 correction kit. 1.900 installed height work? My eddy's have a 1.860 IIRC.

What’s the exact lift?

PBR would be the best guy to ask.

I let the customers pick their springs. I can’t give him spring heights till I cut the new seats. He and another customer were both given dates the end of January which would be fine as I’m still working on both sets.

Ask the cam grinder..?..

 

[RustyRatRod]

Wait till the end of January as instructed?
