What Oil is best to use

I did read about the results of the used oil analysis on the internet. The test results came from people that used Royal Purple and took the time, and spent the money, to have a sample tested afterwards. Based on the results of those tests, Royal Purple products seemed to consistently shear down to a lower viscosity. If you're using it in a racing engine, and changing it frequently, it probably wouldn't matter. If you're using it in a daily driver, and running extended oil change intervals, it's probably not the best product for that particular usage scenario. The formulations could have changed and what I've posted may no longer apply.

Yeah, I know what that is. I'm not talking about joeblow trying to build engines down the street.
Today I was testing at the Tulsa track, several (8 or 9) Pro Stockers had rented it for testing, getting ready for the Kansas Nationals at Topeka this weekend. Started raining after I got in only three passes, but I did get to visit with some of the guys I usually talk to. One is Mike Edwards, friend for over thirty years, and presently the NHRA Pro Stock national record holder, points leader, and appears to be making more power than the rest evident by his normally higher MPH.
Mike is the one that got me to change to Royal Purple when I was buring the ends off push rods. His engine guys have tested several oils, and have had analysis done. I asked about this again today, over some posts on this thread. I asked if he was still using Royal Purple, his guy (Alan) said "absolutely". They have had other oils tested, and some look better according the the guy in the lab's opinion. Many that "tested better" hurt push rods and lifters like what I used before, but did not perform like Royal Purple. He said his stuff last better, stays nicer with "Royal Purple, so he has kept going back to it. Saw their decals on a couple others there today too. The engine builders from ANY of those cars today knows much more about this than anybody on this message board. Those are the most powerful V8 two valve engines in drag racing. 500 cubic inches turning over 10,000 RPM, with over an inch of valve lift with valve springs that make my 1000 lbs open pressure look scrawny. That is harder on oil than anything you guys are doing.

Have to wonder, you some of you guys consider an infomercial like this a "fact"?
If you want to base your choices on silly demos like this video, instead of real world results people are getting testing with real highly stressed engine, that is your privilege. Slamming a companies product over useless demos like this shows a lack of character.

TECH Regular
Bottom line?
Any high end full synthetic with a good filter in the proper weight will keep almost any LTx happy with regular changes. Assertions of superiority between good high-end full synthetics amount to splitting hairs IMO. They're all good, and I'd be hard pressed to say one is much better than any of the others.
Mine has had M1 10w30 and a Delco PF454 or 1218 every 5k since day one. I'm at 108k miles. It's apart right now actually for a heads/cam swap and oil pan gasket replacement, everything looks good and clean.

Easiest way to bump compression is thinner head gaskets. What cam are you running? What crank are you using, forged or cast? Looks like you fell for a typical catalog build. What is your head gasket thickness now? Give us a full list of parts well see if we can help salvage this.
