GTP 420 cam, 853 heads with low mileage 918 springs I am going to a little more radical setup so I have no use for this stuff now.
Heads are 853 castings with about 75k miles. no problems at all. complete and assembled with rockers, comp 918 springs (only 500-800 miles on the springs), and valves. ready to bolt on and go or send em for porting. They already have the springs to work with this cam if you want it too.
GTP 420 cam. I emailed GTP to get the exact specs on it and this is the response I received:
I'll sell it all as a package for $450 shipped or I will go 250 for the cam, 200 for the heads and those options would be PLUS shipping.
Also have a stock ls1 intake for $50, stock TB for $50.

that number means 226/226-591/591-112+2. this is one of the best
street/strip cams i have with out going to monster specs to beat up the
valvetrain. needs good stall. will go to 7200 + with right valvetrain. chris marsh put this in the 10's

How many miles on the camshaft? Do you have any pics? If so send to fhuff1@yahoo.com. Do you have any dyno #s or track time with this setup? What kind of retainers on the springs? Thanks Floyd

sorry, I was just thinking I forgot to mention the age of the cam. I installed it the same time as the springs.
Stock retainers. if they were titanium the price wouldn't be so low
I'm selling the heads at stock head prices with $200 worth of springs and installation labor already performed, not to mention the cash I spent on tools to do the job.
I hadn't dyno'd it yet, but on my heavy convertible I dropped from a 13.95 to a barely tuned 12.65 with this cam, a converter and headers. Everything else in the motor was stock. I know it had more in it but I was waiting for my ls6 intake before I had it dyno tuned. I have the intake now but decided I was gonna go with new heads, solid cam, etc. Like I said, a more radical direction with the car
