ProComp/Speedmaster aluminum heads

So ur saying that u wouldn’t check guide clearance or get a decent valve job. R u just gonna run them out of the box? Kim
I'm going to check the valve clearance and I'm going to check for any leaks in the valves. I'm not going to get a fancy multi angle valve job yet. I doubt if I'll do any porting yet. I would kind of like to see what they do more than less out of the box. Then I can tell what any work I did to them was worth. I don't think I would void any kind of warranty if I just pulled them apart check them and put them back together. I reckon if they can hold up in their stock forum I'd feel better about putting more money into them....
