Help--7/16" rocker studs?
I have read and heard that there's an advantage to 7/16" rocker studs
if you use an after market cam. I have a comp cam, 214/224 dur@050,
563/560 lift, 112 deg LSA.
What advantage, how much HP, would I get from the 7/16" studs? Wear?
The LT4 and LT1 use 3/8" studs and RR's from the factory (well, the LT1
didn't have RR's but anyway, 3/8" is factory). I understand that there's
more flexibility in the valvetrain with the 3/8" design, I just don't know
if that makes a real world difference.
Thanks!

How much you will "gain" is negotiable. You will see the difference in the higher RPMs (or all over if you have beefy valve springs I guess) where more valvetrain deflection would be expected to be seen. Other things like titanium valve spring retainers also lighten things up and help reduce flex.

You will have a more stable valve train. Next step would be stud girrdles. With the spring set pressures I think you will be fine with the 7/16. Arp of course.

Don't make the change to 7/16's studs for the reason of trying to gain HP, make the change to get a more sturdy valve train...you would never notice the fractional HP gain (if any)
