W2 head porting observations help needed!

replicaracer43 said

Then I pulled out a bare, brand new later W2 casting, with the factory out of the box valve job, 2.02 valve, they flow 234@ 500, with no work whatsoever, immediately back to back. I know the actual flow numbers seem low across the board, that could be my bench, but as a comparison, 20 cfm increase seems a step in the right direction, but I feel it needs more. The short turn in the early head has a narrower, more oval shape, where as the later head it looks wider, and a bit flatter. Like to get some opinions from some of the head porters on here, help me go in the right direction @pittsburghracer @PRH @yellow rose @MOPAROFFICIAL ..... ANY advice is GREATLY appreciated!

I'm guessing you know this but double test everything and make double dang sure you have the chamber Edge lined up really good with the bore on the straight side of the intake. If you don't, it will fool you towards over working a port.lol

Get that bowl that 85 or 90% you could take a bigger but not up into the seat or valve job because you want to keep a venturi/throat under that. make all the 'bowls' the same, farside ...and then deal with the short turns. Snap gauge the better head and check agaisnt the lower flowing one. Make the adjustments necessary to make it fit and blend it

I know you know NOT to 'flat ramp it' off the valve job and back, so just lean the head back with light and get it uniform across the top as it rolls. You don't necessarily want to copy a aluminum Speedmaster head let's just say. You know what i mean.
