Which roller rockers?

Guys;

I'm looking at roller rockers for my 302 build. I see them listed as 5.1:1 and 6.1:1 with 7/16" studs. Can someone describe the differences here, and which would be correct for my mostly stock 302 application? Thanks very much.

1.5-1 would be correct but check if you have stock heads they might have 3/8 studs.

Re: which roller rockers?

I would recommend Comp Cams Magnum rockers - they are stamped like the OEM but roller tipped and more rigid than origional - fit 3/8 studs which you most likely have and are 1.52:1 ratio. They will fit a stock or slightly larger valve spring with no intereference problems and are very reasonable - like $170 per set

Thanks Guys! 3/8 studs, meaning the studs that hold the rockers on themselves? I will check out the comp cams ones; sounds like a good deal. I was looking at Rick's for like $380.00.

Yep, 3/8 is the stud that holds the rockers.

Re: which roller rockers?

I'm looking at a part number 1417-16 from Comp. Cams - is this the correct part number? $198.00 with free shipping. Thanks very much.

We had to set the aluminum needle bearing ones up in a milling machine and clearance them for larger springs.

I like Crane "Gold Race" roller rockers for a performance application

If its more "Street" the Comp or Crane "Gold Race" will work fine

If you have guide plates - the 1412-16 part number will work and are about $40 less - if no guide plates for the pushrods then the 1417-16 is the right part number because they are self aligning. Summit has the 1417-16 for less $177 plus shipping which is probably $10.

Do it once and for all , spend a few bucks more and go for pro magnums. These are rebuildable .
