Patriot "LS6 style" heads with what cam? What's the biggest cam that can be run with the PP LS6 Style stage II heads? 2.02" intake valves. GM MLS gaskets. WITHOUT FLYCUTTING. 59cc combustion chambers.
I'm considering switching for the simple fact that the heads I have now have me limited to this size cam, basically, and I want to have the option to go bigger. And the increased compression would be nice, too.
I actually drive the car. 50miles daily and sometimes more. But I'd like to put down a little more power under the curve. A taller curve

With the stock valves in those heads you will gain more from compression than the 2.02 valve and will allow more piston to valve clearance.
233/240 .646/.609 110+2LSA 108 ICL custom grind comparible to a g5x2 ground on a 110 with more lift has the right valve events for our intakes
It makes good lowend torque for the size of cam it is

No this is a cam Patrick G spec ed It will fit In a stock headed LS1
Ive run it through a software program ''DESKTOP DYNO 2000'' Its not exactly accuarte but then again its not guessing ethier . COMPARING THIS CAM to others on the market this one make mores torque than other medium to big grinds .It has the right valve events

Not gonna mill. No reason to mill them with an already low 59cc chambers. And the 2.02" valves will be plenty. I'm just mad that I can't go anywhere later with my setup. It's a great setup. I bought it thinking it would be my last mod. Oh the lies we tell ourselves!

You probably need to call Gunnar at Patriot to find out what the valve drop is on the Patriot heads you want. Once known, you can better estimate how much duration you can squeeze in there.

I emailed him, asking what cams are being ran, but he wasn't as helpful as I'd hoped. I was hoping a "cam guru" like yourself would know what people are able to run. Does the above mentioned cam sound right? It's one you came up with, they're saying.

I think with the 2.02 valves you might want to clay that piston with any cam bigger than a 224 . why not 2.00/1.55 valves, they seat much closer and allow more p/v clearance

cam should make 410 -420 rwhp 400 rwtrq cam only about what the g5x2 does with more lowend . with trickflows and single plane the program spit out 
508 rwhp 441 lbs ft trq 
thats around 600 flywheel horsies 11.5 :1 346 ci

Well, for some reason the Patriots don't come with smaller valves. But I'd say if I ask, I can get them with normal sized valves.
So tell me then: what heads to people use to run big cams without flycutting? I mean, I didn't realize it's so friggin' hard to put a set of heads on a car. Why change heads if you can't even run a decent sized cam? I'm sure that very few people are planning to flycut.

the trickflow Ls1 heads have the most piston to valve CLEARANCE $$ next would be Etp's $$$ If your not willing to flycut stock pistons for power then your stuck with smaller cams or maybe this is the wrong hobby for you . want to learn right ?. 450rwhp doesnt knock on your door . If all else fails ,pay someone to do it for you. Call Patriot and ask them the valve drop so you will know if your valve will collide with your pistons.
