I have the older stealth heads on my 505" stroker. They were mildly ported. I think they flowed in the mid 290's CFM range?
I used the ISKY 8005A valve springs with Comp 748-16 retainers and 10-degree locks.
The cam is the Comp XR286HR-10 Hydraulic roller 236/242 duration, and 0.617"/0.614" lift using 1.7:1 ratio stainless steel rocker arms.
The cam seems fairly mild in the 505" engine. The engine is the 440 source kit, 4.25" stroke, 0.030" over 440 block, 7.1" rods and 17cc dished pistons. Compression calculates to about 10.3:1.
Right now the engine has a RPM intake and small 770 cfm carb and I have the rev-limiter on the Crane HI-6 set at 6,000 RPM and since my original Tic-toc-tack dosen't work with the CD ignition, at the track I was just shifting when I hit the rev limiter.
I will be replacing the RPM intake/carb setup with the Edelbrock Pro-Flow XT fuel injection with the 44 lb/hr injectors. The throttle body is supposed to flow 1,000 cfm, so it will be interesting how it runs after the induction swap?
