Ok - have I missed something - what about the new symectrical head that was shown in the latest Pontiac mag - any info ????

[slowbird]

You can find info about them here http://www.rolandracing.com/index.html. Call or email him for more info.

[cgeise]

yea - i looked - kinda sparce on info - ie - flow numbers ect - any one have any good info on this thing - projected potencial - ect ect - or is it a one off casting that no one will ever see ??????

[Jeff V]

Alot of info on the P4P website.Nothing mentioned on this site.I guess they didn't want to step on any toes over here.

There are no flow numbers yet, dude is slated to get one of the first pairs to flow and test on a 505 I believe.

BIG problem with the head IS (IMO)- because of the canted valve you need a piston relief for the intake valve- not a bolt on deal unless your building an engine from scratch.

To bad that when they went to all the trouble of design - they didnt set it up for symetrical ex also - and get rid of some of that heat in the center of the head -

Have a look at the video below of a running pair of the CV-1 heads on a test engine.

Then it would be a BBC.

I have a current prototype CV-1 Head. Been in constant contact with Roland. What an awesome looking head.

Will be doing some flow testing and mock up work this week.
He is currently working on a 'Victor style' intake to match the higher flow numbers this head produces.

I'm working on the street application of this head (88 cc's currently) and looks to be able to achieve close to 100 ccs plus for big cubic inch turbo and supercharger applications.

Nice thing about it. Doesn't need an offset shaft or lifeters to achive big flow numbers. Plus the ability to use an over the counter 1.8 BBC style rockers.

Stay tuned.

This is going to be around $2995.00 for a complete set of heads and use your RA IV or E-head style of headers.

These were intended to fill a gap in the Pontiac marketplace.

Low cost heads flowing big numbers for street and strip application. But flowing big numbers Out of the Box over a set of E-heads and also for race purposes. Looks like The head can come without the pushrod locations driled for an offset rocker and even bigger numbers. Will get into this later. He is also designing the same head with EVEN bigger ports as a race version. With people already bitch*in about the cost of headers to buy a set of E-heads. Well you know where I was going. LOL.

Dude- any work around for the valve relief with an assembled shortblock?

Are you going to have flow numbers this week?

Haven't had a chance to do anything yet. Been sic for 2 days and trying to get some other work out.

Trying to do flow mods without geting into porting as an out of the box set of heads in the $3,000 price range. Plus after we get valve angles the head likes will get into opening up the chamber for more cc's. Then opening up the chamber & flow for the bigger bore IA blocks.

Then we will get into MINOR pocket porting that anyone can do.

I'm into the backyard mechanic deal so people are offered an AWESOME head............ for the masses and grinding to improve flow that my 3 year old nephew could do. LOL.

But will be doing a mock up to check for clearance with the current IA II block, hyd roller and solid lifter plus a 1.8 BBC max ratio rocker.

Everybody likes "NEW HEAD" !
These heads are shaping up to be the champ.
They did post the SBF SVO intake wasn't big enough to let the these breath.
Huge power potential for very reasonble money.

Dude-

will the mock up on the IA2 representative of an OEM block in terms of valve relief etc etc?

Do you know if the valve relief is needed in all applications? OR does it depend on deck height, cam specs etc?

John

[Skip Fix]

Ken you mean I can't use my $50 swap meet headers??

[WARPed]

With the conversation I had with 7t2cv the large chamber (deeper) with a .600ish lift cam there was no valve relief needed on the 455 test motor. I am sure they will go more into this as thing progress.

FYI- the e-e-heat issue has been addressed since day-one of the design (see posts on P-4-P site).

HAHA, LOL, I stand corrected.
