This isn't 1975, you don't have to adjust the valves with these engines. Hydraulic lifters compensate for wear over time. Just get lifter preload set and leave it at that lol

When it comes to doing valve jobs 1975 is easier and faster than 2005. Having to measure each valve and cut it the the correct thousands takes time unlike with adjustable valves where you just cut the seat and the valve and throw it back together.

Yeah but LS stock heads flow sometimes more than ported SBCs. I think what you were talking about was adjusting valve lash and not just adjusting valves.

Lol valve jobs don't even take that long to do if you know what you are doing. Also, no LS heads won't fit on a small block.. no one is talking about SBC engines.

Ethan [ws6], you sir seem to be a bitch. I'm sure I've did a many more valve jobs than you. And in fact there is talk about sbc engines. On this same post actually.

Well it sounds like you suck at doing them. If you're not precise and consistent with the valvejobs, you can end up the chamber volumes measuring all over the place. It doesn't matter if it's s stud mount or pedestal type, you would want to be consistent with your valve drop.

Lol what. You are the one that brought up SBC. OP specifically asked about 241 heads. Also, he's talking about valve adjustment. Not doing a ******* valve job. Even if you have done more valve jobs than I, which I doubt, your knowledge seems limited. No need for you to get butt hurt.

That will be enough guys. OP came on here asking a question and looking for help. If all you want to do is troll and talk smack, find a ricer forum.

That is a very scary comment, please share with us where you work so we can all avoid such a shop like the plague.

A friend built a gen 1 and checked PTV at the 4 corners and it was fine, only later did he find out that the valve job depth varies .038 and several valves did hiton the inner cylinders.

Far as asking about the 241 heads specifically how about the gen 3+ motors are nonadjustable.

This should be a strong lesson to everyone else about who you trust to do work for you.
