Intro to a port job

They are sunk for sure @ 1.770" IH but what is the goal? 400HP-don't bother, 500 hp go for seats. That's a ton of work and only worth it if.....J.Rob
Yep, put a headstone over those fkrs, theyre buried!
Agreed, no need going broke if the goal hp doesn't match the dollar spent. Good thing is the seats I can do for a lot less than most, if absolutely needed. I know what I can do with the right seat height, that's the thing.
The goal with them is a fat low lift with about 255-260 cfm by .500 ..... the sunk valves aren't a great way to start chasing good low lift #' s.
