You try different things to see what works. That can be expensive, but it puts you out front. While some people just follow along with what other people tell them works. Stan

It’s pretty obvious he has no intentions on spending $1500-$ 1800 (depending on the brand ) on a rocker Shaft set up. Because he’s afraid of threads pulling out. LOL

How about a compromise in this discussion, if you buy a set of KRE heads weather there D-ports or high ports make sure you check them to make sure the threads aren’t compromised from the get go.

The studs are 7/16 and you only torque them to 35 lbs. Kinda hard to pull the threads at that torque.

What I would like to know is how many of those people really needed to be running a Stud Girdle and didn't?
Also here is Graph of how CR changes with added stroke if volume after piston starts the same. Stan

With a ported E-head 550 hp is very easy to make. I like you line up of cars, real nice variety.

The Peformer intake is a "turd" in a 455 build at the power level you're heading for.
No advantage whatsoever going to a 4.25" stroke and 6.8" long rods vs stock strokce and 6.625" rods assuming the same type of rod and piston. The shorter rods will have a little less reciprocating and spinning weight and yank the piston around with a tad more authority, but power advantages at the RPM range then engine will run in doesn't make the 6.8" long rod a better choice. Far as intakes, the T-II is excellent, but requires at least a 1" spacer to show all it's colors, proven from both dyno and track testing I've done with single plane intakes here. Far as heli-coils for aluminum heads, nice upgrade IMHO. KRE didn't heli-coil for the rocker studs early on and were also using thick guide plates and relatively short threaded rocker studs. This didn't allow enough thread engagement. I caught the problem early and told them about it.......

Are you talking rear wheel or Flywheel numbers here when you say 535-550? I'm assuming rwhp from the context, so that would be approximately 650ish flywheel hp?

Cliff while a 1" spacer may make the Torker II make better HP my pump gas HFT 455 with a 1/4"x3/8" angled spacers is making 550-575HP through a TA air cleaner! A SD modified Holley intake dynoed the same as the T2. The Tomahawk is based off that.
The Sniper may not need the "dimples" a Holley needs-which were more than the Demon I first ran on it. I ran the Demon on the HO intake for awhile(picked up a bunch swapping at the track over a worked QJ-even with an adapter))-then swapped it on the T2. Idled better and made more HP both.
