RHS had some issues with their early blocks, and it was resolved. There was a build here, a couple years ago, with an RHS block that had a crack in it…if my memory serves…which RHS made right with the guy eventually. On the other hand, my machinist that I use, who is affiliated with Joe Gibbs, prolly builds 20-30 engines for various off-road racing, that use a RHS block, without issue. I have seen a ton of RHS blocks used without issue, but there’s always that chance. I’ve also seen the snout break off a Winberg crankshaft, so anything man-made has the chance of failure. It boils down to customer service in my opinion, and how the failure is handled.

I hate the Sleeves used on the RHS and Steve being Mr. R.E.D told me yrs ago it's not a option to Darton sleeve the block

Rup1 had a block failure.... what around a yr & ˝ ago... N/a nothing pushing the envelope as far as power.

Then you go back

Damn Google Search ...

Found a answer I knew but really questioned that I really knew what I thought I knew...


Ive got Ls3 rockers or better said already purchased ultra pro magnum adjustable (modified ⁷/ą⁶ stud) mounted 1.8 rockers.


Now I've read numerous posts and threads saying ls3 and ls7 rockers aren't enterchangeable....

A guy used the same rockers i got on a ls7 head. Go figure & who it is or was.

I knew I remembered correctly...

ls7 rocker bodys are around 1/4" longer overall length IIRC

Yeah I seen that... but it's been done even though.

One thing I found interesting was the 'canted valve setup being best (next to a Hemi), but nobody makes one' comment. I'm sure Mast has made a canted valve head for the LS engines for years, their "Black Label" design, and it was available long before that thread (2015) was ever thought of. Pricey? For sure. My .02......

ET Performance then PXR after that it was sold to Mast...
Btw what comment were you looking for when its the truth....

Wasn't me, I was quoting someone. When they said nobody made a canted valve head, I pointed out they've been available for years....

I can't find the post now. Maybe deleted, or I didn't look hard enough. But Corona, I was talking about a post about why someone would comment that there weren't any canted valve LS7 heads available, when they are, all good.

I'm looking at https://www.southerncarparts.com/cor...ms-p-2018.html. These are aluminum but lifetime guarantee..CompCams.
Following the discussion on why use something that doesn't fix the geometry of the valve, I would think roller tips cannot exhibit any side load on the valve stem. What am I missing?

So, yeah, it has been a year now, and still don't really have an answer. I really like the TSP rockers, as they look to be almost identical to OEM except for the roller tip. I know that adds weight. But it also reduces side loading. Has anyone run these in the last year with any success, or do the valves float too easily? I know one well know forum vendor has told me he wouldn't run them, for an entirely different reason. He said the trunnion bearings have a cheap, catchy feel. Any thoughts on that? Thanks guys.

what makes you think they do anythig to help side loading? the geometry of these are identical to stock......call tsp and ask.....

the way i see it, you have 2 rocker options in 2023......stock, or a dedicated shaft mount.....anything inbetween is a money grab

Any roller tip rocker will reduce side loading simply by greatly reducing, or eliminating, the scrub/wipe/friction that the stock non-roller tip rocker produces. Holdener has seen up to 10hp gains from no other changes other than adding a roller tip. Call Tony Mamo.

call tsp and ask them, i called them and flat out asked, "do these have improve the geometry of a stock ls7 rocker on a stock ls7 head".....i was told very straightforward "no they do not"....conversation ended there

i also wouldnt mind knowing what the maximum rated valve lift is at....that should tell you right there

Your talking geometry, and Grinder is talking sideloading of the guides. Two different things. Your both correct btw….

I’m going to run one engine with the tsp roller rockers at .665 lift hydraulic roller and another solid roller to .775 lift with t&d adjustable roller tip rockers because I like to party

my fault, i honestly thought you just throw side load and wipe pattern in when talking geometry.
