Default Valve reliefs?

Doing a 6.0 with a set of 241 heads with 15 thousands taken off them, a stage 4 truck cam, and whatever the stock thickness is on the head gasket. Do I need to be worried about valve clearance? Didn't know if I should get a set of regular flatops or if I need a set with valve reliefs. Haven't had a chance to ask my motor guy. Thanks for any input.

Don't know the cam you are using, so unsure of clearance issues.

But why are you using 241 heads on a 364?

224/230 .553/.547 111+2
And because they're close enough to beinf the same as the 243 for what I want and for what I paid for them.

No piston to valve interference with that cam but you can always turn the engine by hand if it turns free you are good.

I would no worry I done .232 / .620 no problem

Lsa plays a major role in valve events so that by itself doesn't mean much.

I would use a small piece of clay on the piston and check the valves impression. This is the best and most accurate way to be sure, plus its very easy to implement.
