Bill Thomas Tribute heads
Posted by: tknobby ()

You guys have seen the posts on my big valve heads. Most have been for my version 1 heads. These have 1.52" intake valves and 1.36" exhaust valves. These latest are my Tribute heads in honor of Bill Thomas.

I've made numerous sets using 102 heads, 110 heads, 95 heads and LM turbo heads. Right now I am working on a pair of 63 turbo heads which are getting this treatment. I'll cut the seat registers on these today.

Here are a few pictures of a pair of Tribute 102 heads I built. Can't remember which car these went onto. These pictures show the heads with the original small valves slipped into the guides. Just to show the valve head size difference. The 3rd picture shows the original valves in the foreground and the 140 valves to be installed in the background.

I love the work you do! These heads and a tweaked cam (and maybe EFI for drivability) and you've "earned" your HP and torque!

Tom, Very nice work. What does it cost for a set of these heads? Seems like a LOT of machine work. Do they run 140 sized valves or are yours actually larger? I see what looks like a lot of machine work on the valves themselves. Did you machine the backs of the valves too? I wonder what the flow rates are compared to a set of ported 140 heads. It would be interesting to see that comparison.

Nice work, very drool-worthy!

Thanks Bob.

The valves are stock 140. I've not machined them in any way.

The flow numbers on the Tribute heads with 2 carb pads is very close to the stock 140 heads. This is without any special runner porting, just bowl blending. With extra runner porting I can get the flow higher than a stock 140 head. But these heads were not designed to compete with 140 heads. They were meant as a performance replacement for tired, damaged small valve heads.

I get 2000 for the pair of Tribute heads, ready to install.

Nice! thumbs up thumbs up. Hard to imagine the hours put into them. You have a LOT more patience than I do. Not to mention talent!
