Only since you guys are discussing it...I'm selling a set of aluminum
Edelbrock performer RPM heads on ebay right now, part 60259. They are the
2.02/1.60 heads with 170cc runner vol, 60cc chambers. Great heads, just
don't need them anymore. They have been cleaned up and inspected my local
reputable machinist. They were 1100 new, and I am asking 785 for them on
ePay....just fyi. If anyone is interested I would remove them from the
auction and sell them outright. I had them sold for 800 yesterday, and the
buyer didn't realize that they were the 2.02 heads, which require valve
relief...so I gave him his money back and relisted them about 20 minutes
ago, 15 bucks cheaper than yesterday. The must be popular as they sold with
"buy it now" in just a couple of days with plenty of bidding action....
Fyi...

Allan,
What size heads are you looking at? There are size constraints built into
the Tiger.
I'm using Edelbrock E-Street heads (not planning on racing or anything
extravagant) with Sunbeam Specialties headers. They're the same size
externally as the Edelbock Performer heads but without the polishing. I
measured against the stock heads, same external dimensions, larger
rectangular ports. The headers were about the same size as the Edelbrock
ports.
If memory serves Ford Windsor size heads wont fit under the Tiger firewall
(I'm sure you know this but it bears repeating) and the Edelbrock Performer
RPM Intake manifold is too tall to allow the carb to fit under the stock
hood. See Tim suddard's article in Classic Motorsports.
Looking at my SS headers I have to say no, they can't be enlarged. The tubes
are so wide that they used 1/8" hex head bolts and it was impossible to get
a socket on two of them. If you were to "square up the ports on the stock
Ford heads you'd be into the bolt holes.
I can send you pictures offline if you wish showing the port size of the
E-Street heasd and stock Ford heads. I think rthey'll show what I'm trying
to explain.
