what did it flow Mike?

I should be doing my head here shortly

 

havent got it done yet, its still at the machine shop getting the guides installed and the other machine work done then ive gotta take it to another machine shop thats gonna flow it. im guessing ill pick it up sometime this week and take it to get flowed.

as for the intake ports being mirror smooth, well u dont want the ports mirror smooth not only is it a waste of time it doesnt help performance at all if anything it may hurt performance vs a nice 60 grit finish as u see on all my intake and exhaust ports.

Look's great... Wish i knifed the divider's when i did my head

Maybe this winter but hay, keep up the good work man!!

 

The work looks great, including the update pics!

 

thanks guys, i was hoping to have the flow numbers friday afternoon but the guy never called, so ill call em tomorrow and see what the deal is.

I was wondering about that , do you really think that a "knife edge" is better than at least a small radius ? I would have thought that sharp edges were a no no given that air flows in a fluid like fashion .

Just a thought , cheers Adrian .

 

what a night and day difference, hope you get some extra power out of it!

 

ok i finally went and picked the head up today and the numbers are right about what i guessed they would be at .500" lift. they are as follows.......

intake:

.050"- 73.6
.100"- 117.3
.150"- 151.7
.200"- 188.6
.250"- 214.8
.300"- 227.1
.350"- 240.5
.400"- 252.6
.450"- 260.2
.500"- 265.2


exhaust:

.050"- 58.3
.100"- 89.4
.150"- 122.0
.200"- 152.4
.250"- 176.3
.300"- 194.4
.350"- 207.5
.400"- 217.6
.450"- 224.3
.500"- 230.7

im pleased with the results as these are stock sized valves and there isnt a whole lot of porting done to the head as could have been done (i mean it flows basically what i guessed it would). ill find somebody that wants a o/s valve race ported head and as soon as i do ill get it flowed and have the numbers up.

very well done Mike!
just to understand ur #'s, the first # is the lift and the second # is cfm?

 

that is vedy vedy pretty

 

yes sir, thanks guys.



mike

 

what would u expect those #'s to change to if you have used oversized valves?
Thanks

 

4-7 cfm is what ive seen on my neon heads so somwhere around there.

Any reference to a stock head on that bench?
