Normally, the more parts you order, the cheaper (per part) you'll be quoted.
Don't worry about an order needing 1.1 sheets and thinking that the unit cost will be greater than a slightly smaller order fitting on 1.0 sheets.[This message has been edited by pmbrunelle (edited 08-05-2019).]

FWIW, roller rockers don't really do anything for an engine compared to a properly setup and adjusted valvetrain with heavy duty studs. Engine Masters did an A/B test of several sets of rockers, and even going to a 1.6:1 rocker wasn't worth much at all(roller 1.5:1 didn't change anything). and that's on a SBC with 4 more rockers than a 60V6. I personally wouldn't go through the effort to use them unless my engine had a non adjustable valvetrain, and I needed adjustable to correct a geometry issue. ------------------

FWIW - when using a 3400 roller cam block for a 3.4 build - 1.6 roller rockers are required to get the STOCK cam lift of the roller block. Otherwise you're back to the stock .410" of the stock Fiero cam as far as peak lift goes. I also identified exactly which full roller rockers these are for because you can source STOCK 1.6 roller fulcrum-only rockers from a GEN2 3.1 if that's what someone wanted to use.
Let me re-iterate... All roller cam max lift specs are for 1.6 rockers, not 1.5 ratio. Regardless of that, other Fiero owners have shown that the H260 cam ends up with the same specs as the H272 just by using 1.6 rockers instead of 1.5 and dyno results have shown an improvement.[This message has been edited by lou_dias (edited 08-05-2019).]

perhaps the term "full roller" is lost on you?

Allow me to quote myself with emphasis added:

I was simply pointing out, that it is proven that roller rockers aren't really worth anything from a performance standpoint. roller fulcrum, like LSx and 3x00 rockers offer ease of assembly for OEM compared to having to adjust a ball fulcrum, you mentioned the low lift of a stock 3x00 cam with 1.5 rockers, and I showed that you can obtain a 1.6:1 rocker dirt cheap, without having to use spacers, bolt in and go, with 4 spares for well under $100. ------------------

and I have posted that stock 1.6 roller fulcrum rockers from a gen2 3.1 can be sourced for cheaper ... so why do you keep going OFF TOPIC when I stated what this thread was SPECIFICALLY about from the beginning?
Oh to troll as usual...I get it...

Do the 1.6 roller rockers not fit under the stock fiero valve covers? Is this what your product addresses?
