Not bad considering the straight valves. Probably missed it in a previous thread, but what are the runner volumes?

What are the valves sizes and runner volume? These numbers are weak considering they are after market heads. Do you know the deck thickness? I hope they have a lot of room to be ported.

I assume they are backing up after .670lift...... if they are as cast, not bad... probably get a porter to add another 30cfm, otherwise I am not too impressed....... get some more info on em. Runner volume?

Nah...They start at .600 thats why you dont see a .650 just straight .700. If they dont then they have something to prove and will post it up. It could be a simple valve job away from not backing up.

Pretty good size valve on those things for that type of number...Could be a valve job away from making some serious numbers.
