flow figs

Porting is definitely an art form and not something I rush.

My j heads took me a few months of off and on 2-3hrs a day, not really 3 months straight but over a period of.

I looked at them sometimes for hrs while drinking an 18 pack and would do the major ruff material removal while I drank but would be mostly sober while blending the short turn and guide finish work.
I took all the advice I could get and used what was logical to me and then went with instinct and uncommon sense.
I realized after after the guide/pinch and blending the far side wall that I was on my own with the short turn and it was either gonna show skill and flow big or be a junk set of heads.
With the short turn there are all kinds of different ideas on how to do it. I heard lay it back too much and you chance saturation @/after/around .500 lift and that leaving it tall would help it flow through the higher lifts as well as lower, also heard of belling below the seat, basically keeping it roundish or slightly smaller below and into the seat.
I heard the straight shot hump/short turn off of the straight wall needed to be ground out but in a way to mostly trasition the wall/floor to the bowl/seat.

From what I've done with sb 340/360 heads I've learned that a good 5 angle VJ=20cfm and some roof kink/push rod pinch removal=15+cfm, will get you 235-242cfm.

There is a lot more meat in sb360 heads than people think, I did get into the head bolt recess, 1 on each head, but a thick washer with JB will cover the hair line opening on the far edge of the recess, and the cover bolts get studs now too.lol

BTW Thanks Bobby for the info in the pm you sent me.

and thanks to all who contributed to this post
