Speedmaster Heads
The set of heads I ordered during the Black Friday sale arrived today. I ordered the complete heads setup for Hydraulic Flat Tappet Cam.
I have not taken them apart yet, but some things I noticed at first glance
1. Heads appear to be very clean with no shavings etc.
2. All the helicoil tangs are still intact on all holes where they are installed.
3. When placing straight edge across valve stems...the heights are all the same for intake valves, while the exhaust valves are lower, but the same height to each other.
4. The press fit plugs that are installed are installed at various depths.
5. Casting seems thin compared to my Edelbrock heads, so not sure how they can offer a CNC ported version. It will be interesting when people receive those versions.
I plan to gasket match and transition the ports a little better before bringing them into the machine shop to check them out. I will install the heads on my 557 block, 4.25 cast crank engine along with an SPC-8 cam. It will be going into a budget based 70 Firebird that is currently running it's original straight 6.
Let me know if you want any pictures etc. and I can post them up.
