Hi everyone,
I have a 1965 289cid, i recently purchased a set of roller rockers, stock replacement for this particularly engine.
They are the Harland Sharp 1.6ration 3/8"
now my question is, do I need to purchase the guideplates as well? or can they be istalled without them..
And can i install them whit the stock studs???
or do I have to get the other ones to complete the installation??
thanks everyone

If it is a 65 as the heads should have a slot for the push rods (no guide plate required) rather than the round hole they changed to in 66 (requires guide plate) you will most lightly have press in rocker studs which are 3/8 (unless motor is a K code which came with screw in studs) it the engine is going to have a bigish cam and or see a bit of high rpm work I strongly recomend fitting screw in studs

Hey thanks,
so there must be a difference from 65 to 66, maybe it helps, my heads have the 215 code,, and my engine is not he HIPO "k" code, i wish
but the thing is that i should take the tap off and take a look at the guide that you mention,,
Maybe even a picture of it,
but thanks for your help man!!!!

Anyone else??
any other advice??
thanks

Ok, I took a picture of the setup that the heads have,, (stock)
now,
the heads are showing casting numbers, 289,,,, then a 4K26, and a number 65,
do I have to use guide plates with this heads if i wanna install the harland sharp rockers??
and If I have to, do they need machine work??
thanks guys

The picture needs to be in line with the push rods where they come up through from the cam if they are round you need guides if they look like a slot (rounded top and bottom and straight sided, the width of the push rod) you don't!
