Another graph overlay of stock vs ported

Improvements over the entire range of the valve opening. From the bottom to the top.

I want to say that this engine is 300 HP (N/A)
At this point I will finish this topic.

PS The issue price? In Russia the work and cost of parts is $ 2,500. Expensive? Maybe, but it's worth it.

Stayer,

Would you be able to tell me if these dimensions are compatible with the 4g69 spring retainers? If they are not, do you have the correct dimensions?
