[Tigers] Valve train geometry help

[Tony Somebody]

Alan- do you have solid or hydrulic lifters? Also the guy doing the head work should have taken care to make the valve stems the same length. Maybe someone knows for sure if the hyd. lifter will allow for the legth. You have some adjustmet on the roller rockers as well. Good luck, TtT
