I agree.

The CSC-200-STY spring at 100# seat and 180# open is way too light for 6000 rpm especially considering there is some spring tension loss over time.

Re: Started my build

Chevy rockers are used with the stock cam to get the valve lift above .400" where you start to see gains in torque. If you use a higher lift aftermarket street cam that will give you .450" lift with a 1.6 ratio rocker arm then you use the stock 1.6 ratio Ford rockers. As you get near .500&...

The valves are at a slight angle so you will need to measure from the head deck to the closest spot on the intake valve.

The TPS signal allows fuel enrichment according to the rate change of the throttle similar to the accelerator pump.
If it is just a TPS problem I would expect an engine rpm increase without load if the throttle is opened very slowly.
