35% off SpeedMaster

Hmmmmm.... lookin at the ones for a BB...

Any FABO opinions on those before I pull trigger?
 
I too just purchased a set of the CNC'd heads for my drag car. The price was too good to pass up. Got a 'stock' 360 that runs 11.20's so should be interesting to see what they do. I'll let you all know...in the spring!
 
Got the heads.. looks like they'll need a bit of cleanup from the cnc job... But nothing I can't fix.

hell yeah..that would give me an idea of what to expect.. hopefully it's better than cast. HAHA
 
I think those cnc’d heads at 35% off were a smokin deal.

However, looking at the pics........ the valve seat/valve job situation needs some serious attention.
They may be functionaly fine(as far as sealing goes), but there’s definitely some flow left on the table there.
 
The intake appears to be lacking a 3-angle valve seat while the exhaust only has what I can tell a 2-angle seat?
 
if and went i go to use the heads....they will have a complete multi angle valve job....that is why i bought them bare......
 
If anyone local to me bought a set (Freeport, PA. 16229) I could probably be talked into flowing a head for free. I will also do an air-speed check too as that tells the whole story.

Man that is a pathetic looking shortside on the intake side. Its not Speedmasters fault as there really isn't much meat there to work with. At least from what I heard these heads did away with water in the bottom of the port. At least that's what Doctor J used to say when he was still porting heads.

Stuck within a restraint, stock port layout. At a certain point it will only flow more by simply increasing port volume... then It's just an elbow ...at a certain point, shape not ideal, it still picks up by volume

You nailed that. I know for a fact an Edelbrock can flow 318 cfm without moving the pushrod but I flow EVERY port on EVERY head to get there. And usually several times. With the offset rockers Harlan Sharp made me I'm not seeing what I hoped to see but in all honesty I didn't have much time to try things. I will hopefully this Winter

I can't tell for sure, but do the intakes look a bit sunk, like in the thread about salvaging a bad valve job and the flow interference at low lifts? Testing sure would be informative...
 
Lets see....no short turn...two angle valve job...sunken seats.....you guys need to get out of the house ....dam..LOL...

change of plan....going to have complete valve job done on the heads as a valve job will probably help the heads.....
 
^^Right. They will need finish work. Guides will need sized and valve job done at a minimum.
