3/8" Pushrod Clearance
#2
Info with 11/32" dia pushrods. 3/8" might rub slightly on a few holes, but it sounds like a little rubbing is OK.

What heads were you running on that combo, and were they milled at all? Thanks for the info!

I think vettnuts was running bigger pushrods than 11/32, but he might have hogged out the pushrod hole ... can't recall.

I haven't seen 3/8 work on the setups Ive worked on, and what most of use are running for parts, stock rockers,. No big milling, or angle milling the heads, no shaftmounts, ot crappy rockers out there with guild plates, or adjustable cups. I open the holes up to run 3/8 pushrods on heads Im setting up. But I'm running the 11/32 on stock heads

I run YT roller rockers, ls7 lifters, and PRC dual springs. I havent had an issue pulling my current setup to 6600 rpm, but Im looking to eek out a few more HP while correcting my preload which is a bit high.

I have AFR heads, which won't fit straight 3/8". I went with the Trend double taper, which are machined from a single piece billet of steel rod. See this link: Link

We use a lot of 3/8ths on 243s with oem rockers and YTs and they usually do clear believe it or not. If we are setting up heads we will put them on the Bridge port and open them up a wee bit but many fit without work. most other heads they hit on the port on the intake rocker.
