On a calculator.045 stock head gasket gives around 196 ccp the .030 gives 202 engine is 103 48 cam what should I run? I’ve asked around and got different options
The 48? Find a good tuner and 202 is just fine. I personally wouldn't go much higher in CCP though. Tune needs to be good. I ran 205 with an excellent tuner that I felt completely comfortable with. But at that level, I'd add compression releases. Or do the andrews 57 if you're staying in the family (then you might as well have the heads cleaned up).
Compression releases either way. The more the better. I wouldn't fret over 210, even 220 myself. I won't ask you why the 48 when you have the compression to run cams with a later IVC.

I dont think the gain of putting in the .030 head gasket is worth the effort. The 48 is great bolt in cam just get a good tune and ride. If you're going to go through the effort to remove the heads you might as well have them ported, valves, springs etc. that will open up a lot of options. Otherwise just run it.

I respectfully disagree on it being worth it but the real benefit isn't the added compression so much as tightening the squish. Enough that my butt dyno can feel the difference. Especially low end torque. How much it actually improves the numbers I'll have to wait til spring. But power aside even, it's just a more efficient burn. I can tell my motor is less labored even at idle. I did net a 10psi increase in CCP from 190 to 200.
But I suffer from tinkeritis so...
Now if you have to pay someone to do it, then not so much. But it cost me nothing but a good day and a lot of that was carbon clean up. Granted most of that could be accomplished with a spray bottle while it's running.
I do agree it would've been the time for some street porting tho. But I decided to forego that til the bug bites again and I do a BB kit. Hopefully tho, with enough bug spray, that bug won't bite for another year.

I have the heads of and had compression releases installed and I’m doing a big bore 103 kit I have the factory gasket, but was gonna use .030 while I was the if it was an upgrade
It is depending on where it puts your compression. Don't want to bevtoo high either. 210ish is great. 220 is pushing it and would require a spot on tune, especially timing.

I'd argue that if you're touring, 205 plus is pushing it, even with a great tune. Especially considering the nature/quality of gasoline nowadays.
