ported/polished Trickflow LT1 heads

I have a set of Trickflow LT1 heads from my turbo car a while back. They have double valve springs for a hydraulic roller with about 130# seat pressure, good for .650 lift, titanium retainers, and 10* locks. I had the heads completely redone with all new valves, and seals since the reason they came off was a bent valve. They are fresh and ready to bolt on.

The heads were hand ported, polished, and chambers done by a very well known and respected dirt late model engine builder. The guides were blended in with the port/polish job as well. I won't put the name out publicly, but I will let anyone who is interested know who did the work via PM. I no longer have the flow sheet, and I'm in the sticks, over an hour away from the nearest flowbench, so I don't really have plans to re-flow them. But these heads have SICK flow numbers -- the best mid-lift numbers I've seen out of any LT1 head.

I sold my 4th gen about 6 years ago and these were always sitting on the shelf waiting for another LT1 project to roll along. Apparently I am way too interested in old school Pontiac power with my 2nd gen now to bother with another LT1 again, so it's time they go.

heads, as they sit: $1500 shipped
with a set of stock-length hardened pushrods (TFS, I think), Comp 1.6 Pro Magnum roller rockers, and polished aluminum valve covers: $1800 shipped

I have more in them than what I'm asking for, but I know the game... Reasonable offers may be accepted. This is TOP quality. Low-***** won't even get a response.

Re: ported/polished Trickflow LT1 heads

I just CC'd them 3 times each to be as accurate as possible. The intake runners are 212cc. The exhaust are 80cc.

It's a 62cc chamber from the factory with the combustion chamber smoothed out. I got right at 63cc measuring it.

The valves are 2.02 and 1.6.

TTT. Price reduced.

I also forgot to mention, they are set up for running a -6an line for coolant lines going into the back of the heads. -6an is the same size as the stock line for this, but the fittings flow so much better than the stock banjo bolts and are less likely to ever leak... You can simply hose-clamp it on like the stock cooling line at the front and use -6an at the back. I'll provide the fittings and hoses.

Re: ported/polished Trickflow LT1 heads

Thanks. Yeah, they're almost too nice, which is why they've been on the shelf for almost 7 years.

I did get a PM asking what kind of boost these saw. In case anyone else is interested, I ran 16-18psi boost on them from a 76mm turbo with ARP head studs and SCE Titan ICS copper head gaskets.
