93 350 Rockers? 1.5? 1.6?

Im wondering what type of rockers are on my motor stock? Id take a wild guess and say 1.5...

My question is, would 1.6 rockers do any good to get any extra lift out of my RV cam?

1.5. Going to a 1.6 may make it so the push rod will rub the head so the push rod hole may have to be opened up. If you have the stock 93 heads with a cam already it is probally useless to go with more lift since the heads don't flow any air at higher valve lifts. You'd notice more with some better flowing heads

Yeah. I know these heads dont like very much cam at all, I was just wondering what rockers they had. Vortecs are gonna do me some good

[fastredgmc]

Yeah i got the vortechs. lots of upgrapes to do to them unless stating from sctach. if your just using a rv cam go with a l98 heads it wil cost about 100 bucks or so for the heads plus a vavle job and you can still use your intake buy the time you go with the vortech (say 500 heads and 200 for the intake) and just other little things it add easily a 1000 with no problem.

1.6:1 ratio rockers would be benifical because of the lift vs flow
of the OE cylinder heads. the increased lift and added duration
will increase flow.

Even if he has a cam in already? If the cam is big enough already the added lift will do no good, right? At about what lift do these heads "Stall Out" you want lift to be at or just before that point.

1:6 w/ the cam.
