Tweet

dots go to the front they are on the rods right. the rocker look like they were running off the valve stems they should be in the center line of the valve look at your push rod guildes move them to get the valve in the center of the valve stem if you can not do it then use isky adj guide plates is will keep it from side loading the rocker and check the push rods make sure they are the right size not to long or to short . on them rockers i do not care much for them if you want roller i would get a set of crane or any thing but proforms or a stock shoe type with no roller tip oh by the way you do know them valve stem will have to be cut on the stems? to get them flat . and i would get both heads cut flat them holley head some times have crapy finsh on them out of the box . and it looks like the rocker were running on the valve retainers to lucky out did not blow it to hell .do them heads have any push rod guide plates? if not you need some
