The roller rockers I purchased were from T&D.
I think they are the only people to make stock
replacement units for the buick heads.
Mine were about $400 about 6 years ago.
You should be able to pick them up from any T&D Vendor.
You will need taller valve covers. You may
want to check with RJC they are making a new set.
Lifters do not have to be differnt with the rockers.
The push rods might have to be changed.
I have been able to run a stock lenght set before.
Some people have to machine the heads or rockers
to get them to work, but I never had this problem.
With the 218 cam they would not be a bad idea but you
do not need them. Your choice should depend on the budget.

A friend of mine just put a set of T&D 1.65 roller rockers on his factory iron heads. The rocker shaft towers needed to be machined (rocker arms hit the side of towers).

roller rockers don't offer much (if any) performance for the buck......on a very high performance set up (mid 10 and down) there may be advantages

I used the T&D 1.65's on my iron heads and really didn't see any improvement

get a better shaft (like TA makes) and stick with the stockers

 

[turboTURBO]

ok where do i get that shaft???
also is the 85 and 87 shaft and rockers the same???

 

[azgn]

TA Performance

dunno if they are the same, but would ASSume they are (same heads)

 

[turboTURBO]

i think im just going to buy them just to have them since my car is already torn apart...

thanks for the offer, but im trying to figure out how all this works before i go buying some... i dont even know what else im going to have to buy when i get roller rockers..if i can use stock springs and pushrods and everything else... i dont know yet..

you should have no problems,are you heads milled?do you have the stock push rods?who installed you cam?you can ask them,i have heard that if you uc stock heads have the correct lenth push rods you will have no problem,when using alunimun heads people have push rod hole clearance problems,i have been told to stay with the stock or as close to ratio stock1.55,find out from the person who istalled you cam

heavy duty stock style rockers would do fine ..I've always run stock rockers on mine with no problem but I have a set of heavy duty replacements going on now just to help out with shaft flex

contact me and I'll tell you good place for the heavy duty stock style ...alot cheaper than rollers which really arent needed


and yeah 85 and 87 are the same rocker shafts
