Valve pocket/bowl hog tools....

Takes a lot of time.
Like everything mopar, the potential is there if you know what you are doing.
Those / heads dont gain **** more than 20 cfm without spending the time.
It's the floor, and that's what everyone shys away from.
I have a few heads.
/ big valve head ported 195-200cfm is what I get. I'm not trying to set the world on fire, but its respectable. Most of that is under .400...the last 10cfm is .500-.550 and hanging on.

Well, here is "where I'm at". I tore down this slant head I had the other day. To my astonishment, the guides weren't just good. They're real good. That's gonna save some dough........If the head isn't cracked. So, my plan is to go ahead with the 318 valves..........SINCE the guides are good. I am lookin at kits on Ebay for bowl and seat enlargement. Get hooked back up with Mike at B3 to get the geometry corrected and see if maybe I can either port it myself, or maybe get some local help. From what I have read, 75% of the flow improvement is in the bowl area anyway, so if I do a good job there, that will be most of it......hopefully. LOL
