If you have single springs use 1.1 rockers and put 30mm venturies in the 40 IDF's. If you have dual springs use 1.25 rockers and 32mm venturies.
You didn't mention but use 1 1/2" exhaust.
Rant: CB should not sell Panchito heads with single springs. _________________ 2017 Street Comp Champion - Thunder Valley Raceway Park - Noble, OK

I have Panchitos with single springs, and I'ma use the entire capacity of those heads while maintaining excellent valve control. Not everyone needs a ton of spring pressure and heavy chromoly pushrods.] _________________ "A petrol engine can start readily, run smoothly and give every appearance of being in good order, without necessarily being in good tune." - Colin Campbell, "The Sportscar Engine" |
