I know some of you guys have bought the oversized valves from Engnbldr, but has anyone actually installed these valves and have them in a running car right now? I'm looking into oversized valves for a project and have run SI valves in my racecar. What valves would you buy??

I used them in my 75' Duster, they were very nice peices and never understood/had an controversy with engrbuilder. The only problem I had were the bronze guides didn't match up and I bent a couple. I sourced the correct ones through my uncle Gary and it was together. My only arguement is with the engine I build I had wished I didn't waste them on it. I did quite a bit to it, but it still wasn't enough to need the bigger valves. However, knowing what I know know they are the best size I believe for the slant with out running into shrouding problem. Best of luck.

Hello,

Lots of us have em in. Check the search for engnbldr for a relatively recent thread. I have 2 separate sets in 2 engines, for instance.

Anyone ever flowed a set of heads with these valves? If so what where the flow numbers and the port velocity's?
