im going to buy a set of used w8 head.for my 440 sb. what sould i be looking for looking to go mid to low 9's at 3000lb. racing at 0 to 3500 ft .. will appreciate all imput.. im done with this indy leaking junk..

I wouldn't imagine that there is a hell of alot of them out there anymore, but from a reliability stand point I would look at an old Craftsman Truck head. They will have more meat in them than say something off a Pro Stock Truck engine. Ideally you don't want something used up or that has had to be repaired. I had a complete CFE w8 top end that I wish I never sold! Be prepared to put your hand in your wallet, nothing for them is cheap! A W9 head could be another option for you.

if i were you and the goal was low 9's do w9's tons of em out there,that goal should be pretty easy w w9's

A raw Zeus casting (without spark plug hole) is a good foundation for the CFE treatment......

Just like the ones I have under my bed.

what valve size and stem size should i be looking for this is all new to me. thanks

are you sure they still are under your bed?

Mid nines is nothing for W7 W8 W9 or the old Arrignton heads.

Just make sure you get something meant to run on 48 degree blocks. There are some W9 heads that are built for 59 degree lifters and I would not advise spending money going that route. Mid 9's are obtainable with Indy heads.

I highly recommend CFE W8 stuff for anyone wanting to go fast the truck stuff is just not in the same game. But, if mid 9's is all you want I would save a considerable amount of money and go with old truck stuff.

I would consider a R5/P7 , easily goes mid nines and probably cost less
than a pair of CFE heads

Adapters are available to make it a fairly easy swap

w9 would do what your asking witrh no problem

W-5 heads will get you mid 9's no problem. I have a complete W-5 top end from sheetmetal tunnel ram intake to head studs for sale that went 9.50s all day long at 3250lbs and 372 inches...

THE W8'S i have in my basement untouched

the block i am going to use is a 48 degree block . what is the diffrents beteen the cup truck and pro stock truck and a compeliminator w8.

I thought I read somewhere that the only difference between W8 and w9s are that the W9s are lighter? If this is not true then what is the difference?

nice
