Is there a differece between these 2 heads other than the angled valves? Can these head support enough N/A performance to run in the high 11s at about 117mph?

 

Oh, here is a picture of my Tramaro. It needs painting but its almost ready to go.

 

go with the standard valve location. I know someone that has replaced two sets of valve guides in the first versions.

on't ask me why.. the exhaust valve angle were the only ones relocated but both guides wear like nobodies business.

 

What about the stadard valve location in the Trick Flow heads, Do they were the guides fast 2? How much power will these heads support out the box?
