Would these be suitable/advantageous for a mildly modded 425 66 toro engine ?
Has anyone used these maybe ?
thanks mike

Not that it really matters but the first question I'd ask is are they 1.65 or 1.6? Read the add, it says both. Hmmmmm...

 

cutlass ,
1.65 is how I read it -

 

I would figure that they would help with less with less vavletrain stress and you may see a few HP to. Gotta be an upgrade over stock ones.

 

First off you will need to run diffrent pushrods,You will also need studs instead of the stock type bolts and guide plates, I have run the comp Cams kit with succuss and it comes in a complete "Kit" for BBO Or SBO I would avoid those and go with the kit my $.02,I have run these with a .500 lift cam and as fast as low 12's..............Jerr

X3 The kit is the way to go. If you buy the cheap stuff then you have to piece meal the whole thing

 

thanks guys --very useful info --will get onto the kit

 

May I pick your brains a little more please
It transpires that comp cams does not make a kit for the 425 . 455 ,350 etc yes .{ email from jegs tech dept)They (comp cams ) do however, supply the roller rockers to suit . 1442-16 # from memory.
Any geometry hassles with going for these alone ????--guide plates, rods which I own are in good nick .

thanks
mike

I heard that these roller rockers can be noisy. They sound like tapping valves.
