If it was easy everyone would be doing it.

If he could do it, Morris and co can do it.
This is all speculation, but maybe S. Brown and Marcella are involved ?

They don't crack or leak?

None have yet.... But the cores need to be a virgin head or at least nothing larger than the commercially available "380 cfm" port

Still, not sure if these are Marcella's heads. But his work is done all in aluminum. Best aluminum welder on planet earth and he does not like epoxy.
Anyone know how Giro's new bullet is coming along ?

Chris Razer might take acception to that comment.

There are three programs available all based on the Edelbrock RPM head. One is a very efficient 330 plus cfm recommended for combinations up to 700 horsepower. A 350 plus cfm which is recommended for higher horsepower NA builds and max-effort boosted builds. A wide-port 410 plus cfm program which is recommended for 1k plus horsepower NA engines or serious effort nitrous build. Also offered is a 460 cfm program for Hi-ports.

Pretty cool! Is there a smaller highport program available or just max effort stuff? Like something that doesn't need offset lifters

Thanks, just the one program for Hi-ports. We can always hand grind the Hi-ports they're a pretty straightforward head.

Just asking how his car is going.
JM had his own thread here about his High Ports.

What do you think a High Port can do with no offset, no epoxy and a 2.20 valve ?
?

sorry to get off subject but who would be the man to fix a set of leaky [water] hi-ports?

[steve25]

KRE can’t do it or recommend someone?

Our welder retired recently. Chris Razer would be an excellent choice to weld the head.

i had my set fixed with weld, i believe it was two of the middle intake ports, at carlquist engines in waterbury/oakdale ct. (he said it was a muther lol) not sure how far that is for you. definitely pontiac friendly and very capable shop

This may be a good option.


FWIW I've found dealing with a professional welder is a better choice. They will just make the repair and move on to the next job. Professional's will not complain about the difficulty of the job .... They'll just fix it.


I remember picking up a pair of RAIV heads at a very appealing price years ago. Against my my recommendation for fixing them, the guy took the heads to a very reputable head shop. He was told "if they can't fix'm no one can". Well when the heads were deemed unrepairable I purchased them for scrap. I sent them to the guy I originally suggested and $150 later they were repaired. We raced them for several years and then sold them to a nostalgic road racer.... They're still in service today.

Full port job for sure. I've never cut a Victor in half. I save that for dual planes. The only reason to cut a manifold in half that I know of is to gain easier access to hard to reach areas or put an aftermarket manifold on an old four cylinder.
