I have a few questions about motor work. I've tried to search for some info but I haven't found anything. We where thinking of going with either a 416 or 416 depending on what is acutally done to the motor. The compression we were thinking is 11:1. My dad was wondering if there is anything that has to be done the with the valves to run 11:1.

Valves dont have to be changed for either but to run a 426 you have to get a different sleeve.

Thanks

valves are fine, you can of course do the head up for more power, but stock is fine.

ive been running a 440 for 2 years in a 99 EX. stock valvtrain/head no issues what so ever

Alright here's another question. Is they anyway of knowing what kind/brand of cam is in it without setting it up against a stocker like markings or something?

There may be a number that you got get off the cam then call a manufacturer and give them the part number. Some may even be able to tell you if it is from another company.
