No.
I've built a lot of small blocks, street, and limited late model/street stock type motors and can tell you that, with a mild cam like that, 1.6 rockers are probably one of the best things you can do. The exhaust ports really like the higher lift and pay you well for it. The higher ratio will also increase the ramp which will be lazy on that oldschool cam.
I used to run a dirt series that had a .450 lift rule. I would run other tracks that didn't have the rule, and would swap in 1.6 rockers for those nights and it made a huge difference. I experimented with intake and exhaust, intake only and exhaust only. When time was tight or I was feeling lazy, I would just do the exhaust, it got me 90% of the way there.
Roller rockers might be a waste, but not stamped steel.

Well if I ever decide I need a bit more, hopefully I've future-proofed myself with the stud upgrade.

Welcome to the club. I think we're officially up to three members, so that's nice.

Oh, for what it's worth. Next time you (or someone else) need to do this, you probably want something like this:

E36 M3 man, you could have asked before you went gung-ho.
Still, you have the other head to do, right?
In reply to Mr_Asa :
Nope. We're done. But the second head went much faster. Hoping to have them cleaned and at least ready for install by next weekend. Next few days are busy so I'll update when I can.
Oops
anyone know if standard super glue dissolves in fuel?
Not knowing if cyanoacrylite was fuel safe, I did a two minute search. Google said "moderately" which is basically yes. Enough for me to run with, anyway. But for extra safety, I drilled and pinned the thing. Hard to get photos of tiny stuff.
gonna let the glue set and clip the clip and sand it flush. I genuinely laughed when my little ryobi had enough squeeze to grab that .8mm bit. Dipped the paper clip in glue and slid it home. Seems good enough.
For those not familiar with Q-jets, this is a plastic piece the lives in the bowl and serves to hold the float in place. I could have probably run it broken, but I figured I could at least try to fix it. If it becomes an issue, there are a couple carbs kicking around dads shop that could serve as donors.
Im doing the carb now because I thought I was done with the heads. But now the carb is spread accross the bench (1/4 sheet laying across the bed rails) I need to finish the thing before I can put the heads up there to finish the last few details.
Nobody tell the wife that I did this in the kitchen while she was out.
One remanufactured Rochester
hoping to finish the heads today. All that's left is a few seats that still need attention. Which I discovered after cleaning. Really hoping I can avoid having machine work.
all valves and seats lapped into submission, all threads and stems sealed. All moving parts lubriplated. And I mocked up a rocker and verified plenty of clearance, Clarence.
Still need to clean all the rockers then the heads are ready for install.
