If you have any Q's let me know via PM if you dont want to post. I'll always give you honest answers based on my experiences. Unfortunately I wish I had only built the motor one time but you learn...

L19's are going into my build. Intense's widebody G35 has done fine on L17's thus far with no problems, but I wanted a little extra piece of mind.

Thanks a lot. As you can tell, I don't post much in this forum.

We use L19's on all of the motors we build. They've handled 30psi and 1000hp just fine!

we've run them on the supras we build and they have been great. The cost difference in going with L19's is still cheaper than having to machine the block and head for 1/2" which is the only other way for big boost. Save some time and headaches and do the L19's

The L17's are currently on my car. When I add cams and valvetrain I'll switch to the L19's. I have to get rid of the small Borla TD exhaust as well.

If the L17s are torqued adequately they are enough for 95% of the builds on this forum.

Well I'm at 496whp right now. Looking to add the cams/valvetrain/exhaust and get a new tune. I feel it puts me in a dangerous area.

I rocked 19psi on greddy twins with L17s torqued to 85 ft-lbs for over a year, and it ran awesome. Might still stay with them just to see how far they will go, or might go ahead and get L19.

All of the websites that I've gone to say that the BC stage 2 doesn't even need a valvetrain upgrade of any kind? Can anyone comment on that?

Probably doesn't....I have the JWT C8 cams(272) and the only thing needed was different valve springs.

Yeah, it says that the BC stage 3 requires springs and retainers.....

This is just getting cheaper and easier by the second..... or is it?

My engine only has 2k on it since the build....heads have 17k... should I upgrade springs and retainers to go with the BC stage 2?

Stock valve train is fine to more than 7500rpm's all day long. To be safer I wouldn't rev past 7500. Ray @ PFS pushes 800+whp, 8000+rpm's on stock valve train w/ BC stage 2's no issues.

I've never heard of the L17's, are they the same as the ARP 2000 11mm headstuds?
