I would rather show it that way to avoid someone being disappointed. I remember how disappointed a friend was when he built a complete Performer RPM head/cam/intake/carb combo and gained nothing at the track over his previous D-port combo. He did eventually pick up after other changes but same money could have got him better results still using his D ports.

I'd love to see what Calvins Quest or Fusion ports would do for your car.

Right now, there are 9 different port versions of CV1 heads you can buy. From a 235cc port up to 326cc. Rocker arms are cheap and easy to find at any drastrip if a guy thinks new is out of the budget, or if a rocker arm breaks. But the thing is the geometry of the valvetrain has proven to be right on without any alinement issues, even on a 9000 rpm engine. And if there was rocker arm issues, you know at 9000rpm a non shaft rocker arm set up would show it!!!

YES ! It's an improvement over the normal Pontiac exhaust. Everyone that has used this option has went quicker.

A little know fact is that you can call Rolando at RP Motor sports in Vaughan, Ontario, Canada for a Jesel setup......

As the exclusive VAR (we paid to develop the setup with Jesel) he'll will put together a price for a complete "Jesel setup and have it drop shipped,, give him a call at 905-851-2033.....

he doesn't post online, in fact he don't have a computer! Does things the "old way".
as he puts it unless it breaks. It hasn't broke.

Targa · 10-17-2010, 06:07 PM

Lots of good info there guys, thanks.

One other question about the rockers is, not running a rocker stud but going with a shaft system.

Not the T&D money though.

Didnt I see a different brand name that others were saying would fit but would take some work?
Phobes? Or something like that... cant recall.

Bad69bird, had a all day/all night party I was at yesterday.... sorry I didnt notice you called till about 5am.

Shoot me a PM when you want to have me call you back.

goquick · 10-17-2010, 06:15 PM

Right now Yella Terra "independant" shaft rockers and the T&D shaft asystem is all that actually fits unless Jesel finally did make them in the last couple weeks.

Targa · 10-17-2010, 08:31 PM

OK, so the YT is in fact a shaft system? Like Doc's T/A? (aka Bankbook)

I have not been able to find any pictures on the net of the YT's so I could not tell if it was a shaft system

That was what I wanted to run but didnt want the T&D price tag is all.

bad69bird · 10-17-2010, 10:19 PM

Joe,

Good talking to you. Sorry for the abrupt ending on the phone...gotta love kids! I'll give you a call later this week.

bankbook · 10-17-2010, 11:34 PM

Mine are the T&D's as in the picture.
The Yella Terra's are half of the price.
I do believe that Jessel is now available for the CV1 as well.

Targa · 10-18-2010, 03:08 AM

Doc, my question here is... are the YT rockers a 'shaft system' like yours or not?

Like I was saying, out of the whole net, I can not find a damn picture of this rocker set anywhere.

Every place has 'no image'.

Thanks.

goquick · 10-18-2010, 03:35 AM

a picture of the yella terra rockers;

Targa · 10-18-2010, 08:05 AM

ahhhh, so NOT a shaft system.

So what rocker ratio is used on this head? What works? Any that do NOT work?

Anyone used the Scorpion rockers for this head?

And finally....does anyone make a lower cost shaft system than T&D?

Sorry for all the questions. Just want to know all the options is all.

Actually they are a shaft mount, just different than others.
I think at this point you should call Jim at Roland Racing (417)209-7395. He will have all of that information. I dont think he would mind the call even if you are "kicking tires" at this point.

BADDTA · 10-18-2010, 08:35 AM

Targa,

Look closely at that pic. Those are shafts. The pushrod cup is where you set lash. There is no rocker stud, it's a bolt just like the T&D. Also no pushrod guide plates.

Targa · 10-18-2010, 08:51 AM

I guess I was looking for the same type of shaft system.

Yes, I know they have a shaft as do my other roller rockers from way back when.

I was just looking for the same system as what Doc has. Like when you have the two rockers next to each other, they shared a shaft.

Thats seems more stable than 1 rocker stud to each rocker.

Anyway.. now that we have that cleared up...lol.

Has anyone used or heard of Scorpion rockers used on this head?

A member here offered a set to me at a very reasonable price and was wondering if this was a set to use or just go with the YT rockers.

My cam profile will be about .750 minus lash.

Thanks.

On a canted-valve head??

BruceWilkie · 09:41 AM

Scorpion rockers themselves are a very good rocker. Lots of spring/stud clearance strength etc.. Will they fit I guess is your question. Probably if they are a BBC rocker they will fit. The set I used on the 528 Ford I built didnt seem overly large. Less square than Harland Sharps. I think a call to Scorpion and a call to Jim you should be able to find out dimensions and determine if possible clearance issues. I doubt any but checking first is a good thing.

BTW the Ford was .767 NET lift and I saw no difference from checking springs vs Manley Nextecs. That combo ended up in a 3000 lb stang 8.97 first pass.
