Piston valve clearance?
Piston valve clearance? I have a stock 95 lt1 out of a caprice and want to swap the heads and cam. I picked a pair of aluminum F body heads and a comp cam. My question is will that engine handle a .576 lift cam? I know I have to change the springs and I will be running the the stock ratio rocker arms.
How does it sound like an XFI cam? There are plenty of profiles out there that could end up with a net lift of .576 lol

The Caprice shortblock is the same as the f-body.
The aluminum heads are NOT an upgrade without porting. That said the iron heads can not handle that lift without machining.
Why don't you tell us what cam you picked because the Comp cams listed rpm ranges are WAY off and you probably picked a cam based on them and will endup with WAY too much duration that way. Generally for a stock shortblock you want to say under 230degrees on the intake. Probably even better to stay down in the mid 220s in most cases.
The cam is actually for the TPI engine I had but I sent it in to have the dowel pin replaced so I can use it in my LT1 because my 70 camaro is getting upgraded from a TPI to a LS1. I thought the lift was bigger but its .570 in/.565 ex. Adv duration is 268/276. I just want to make sure I will have clearance which is all I am concerned with...
