[DeTomaso] Fwd: What Headers match new Edelbrock 2V Performer RPM Heads ... ?

When I mounted my GTS headers onto raised-port heads, the left side hit the tank. Its possible to slide the tank outboard about an inch using the stock hold-down strap. The heat shield may need a dent at the closest point, and by bolting the offending header to a spare head, then heating the critical pipe with a torch and bending it a little, clearance can be produced.
My problem was, after clearing the tank, the 3-bolt header flanges hit the stock spring/shocks. To fix that took a pie-cut in the small collector area, rewelding and a similarly altered exhaust pipe connection. Good luck- J DeRyke

Hi All,
I have not heard this one before, but some mechanics here in NZ are
telling my friend that the exhaust ports on the Edelbrock 2V
Performer RPM Aluminium heads (part # 61629) are raised from the stock
head location? and that they are an inch higher than stock...? I find
that very hard to believe.
I think my friend just needs some correct Pantera Headers? Basically,
the headers he has are hitting the gas tank shield on the drivers side
and the flange is hitting the suspension on the passenger side.
The headers he has are Pacemaker out of Australia, see his email below.
Your advise would be greatly appreciated.
Thanks, Ed

Hi Ed,
The great news is that the engine and gearbox went back into the
Pantera early last week ... the bad news is we've hit a major
problem. I think I might need some advice from the POCA community,
as I'm sure someone else must have struck this issue.
When the engine was rebuilt, we changed over to new Edelbrock 2V
Performer RPM Aluminium heads (part # 61629).
Seemingly all of the mechanics failed to realise that the exhaust ports
on these new heads are approximately 112 inches higher at the outlet
than the old headers. Accordingly when the guys tried to fit my
2-inch Pacemaker headers back into already tight spaces, there's no way
they were ever going to fit ! We can almost get the right side
headers close, but the gap on the left side between the heads and the
fuel tank is now way too small.
Given the general lack of knowledge about Panteras in New Zealand
(there's only a dozen in the country !) I'm desperately trying to find
a cost effective solution. The options appear to be as follows:
1. Ask if anyone in the POCA community has these particular Edelbrock
2V Performer RPM heads installed - if so, what make/model
headers are they running ?
2. Have some new 2V flanges laser cut, and then butcher my existing
heads by trying to cut/reshape/weld them onto the new flanges
(approx US$2,000)
3. Find someone here to make a set of custom headers from scratch
(approx US$5,500 and a 2 month wait !)
I can see that Pacemaker (an Australian manufacturer) produce units for
both 2V and 4V heads for a Ford 351C engine, but of course there's
absolutely no guarantee they'll fit a rear engined Pantera ...

I'm really, really nervous about ordering a new set of headers through
Ebay or offshore unless I can be certain that they'll bolt straight
into place.
Any help would be very much appreciated Ed, as we're at a bit of an
impasse at present - work had ground to a halt until we can solve
this problem. Can you see if any of the POCA members have an easy
solution for this problem ?
Cheers,
Dave
