He had 63cc Chambers and 2.04/1.57 valves and ran a 0.040 gasket.
Mine have 62cc chambers and 2.02/1.57 valves.
Is it safe to say the difference in valve size will make up for the difference in milled surface loss?
Maybe running the 0.045 cometic would give me a little more cushion and not lose too much quench?
I am looking at around 11.2:1 SCR and 8.9 DCR correct?

Since you will be measuring anyways to ensure proper clearance, I wouldn't sweat it too much. On paper things can look perfect, but in the car things can and do change due to tolerances.
I'd keep the .040" on it if you're committed to fly cutting if it's necessary.
If I use the 0.051 MLS gasket I will end up with 11.06:1 SCR and 8.75:1 DCR. And I will avoid flycutting (hopefully).
If I use the 0.040 cometic gasket I will end up with 11.38:1 SCR and 9.00:1 DCR. However I would definitely have to cut pistons.
Are these differences in compression worth my time and money to flycut the pistons in your opinion?
Thanks

I don't recommend everyone do this, but some do not want to fly-cut and still have a max effort combination with the biggest cam they can fit in it.
In terms of being "worth it", I have some customers who are willing to spend 1k dollars for 20hp. Some don't want to spend more than 350 dollars for 20hp. Being "worth it" is relative to the person who is forking out the dollars at the end of the day.
I'll tell you that the .040" gasket versus the .051" is worth about 8-12hp and almost just as much torque. If that is "worth it" to you, go for it.
Now if you're going to fly-cut and want to run the .040" gasket, I would have your local machine shop mill the heads a little more. Get the most bang for the buck! That's just my $0.02.
What type of fuel will you be running? Any power adder?

I'd like to take the next year to build an iron block 427 to handle an F1X procharger but will be a costry build and will need a year to gather funds.
It does lose a little torque(8-15) from idle to 2750-3000rpm depending on what headers, merge and exhaust you have. The SNS Stage 2 loses around (4-8) in that same RPM range. Again depending on merge, headers and exhaust
I'd also ditch the Flowmaster muffler for a Magnaflow or a Hooker Aerochamber. Proven HP gain.
A guy at a local shop will be porting up a set of milled 241 heads for me. Sounds like the ending compression ratio will be in the 11.2:1 range so I'm guessing around a 60cc chamber, which also means about .040" milled off of them to get that CR. I'm waiting to hear exactly how much has been/will be milled off but I think I'm close.
Now...with the Street Heat Stage 2 camshaft that I have sitting here in a box, will I run into PTV issues with heads milled this much? I realize that I will need to run shorter pushrods also (7.300-7.350?). Again, I will not be doing the install. My tuner and the guy doing the heads is confident that we can see 430-440rwhp and 400+ft-lbs with the milled/ported 241s and your camshaft (if it will fit...), 1-7/8" longtubes and offroad X, LS6 manifold and TB, AFE CAI, ASP 25% underdrive pulley, 36lb injectors.
Thanks for any info on this.
This is the second time I've dealt with Tick. The first time the let me get in on the group buy for the Tick Adjustable Master when I was a day late and STILL didn't charge me shipping... TO HAWAII!! WHOA. This time I was/am in the market for a head cam setup. Martin was very patient with me, explained everything for me, took the time to spec out a whole setup for me and so far I couldn't be happier. I realize there are a lot of great choices to go with in the LS world, and most of them are great, but so far their customer service with Martin in particular have been outstanding. Thanks for everything so far Martin, I'll be calling soon about those TF heads we talked about!
