Porting small block 915 j-heads
Hi PRH,
Yes there is a complete 340 J head that is ported by Weslake's here.
The machine shop where I used to work in the Noughties had a flow-bench, but sold it in 2002 when they moved premises, so I never got to use it!
I have several heads that need flow testing from Weslake in the 70's and few others too from 'porters' here in the UK too.
Rob Loring of ICE Automotive did a very nice set of raised port BB heads along with Jeff Hauser and USA's finest Koffel's too.
Not seen many trick S/B iron heads as they are less favourable here in the UK?
I always use an 'E' gauge when doing the 'pushrod pinch' normally get around an inch with smallblocks and a 'tad' more with Bigblocks.
Some Bigblock heads I have are 'raised port' approx 1/8" to 3/16" but the 'ICE' heads are nearly 1/2" with 'flow-guides' cemented into the floor to make the port 'normal size again.
Better with pics I think.

ps pushrod pinch is always, 'grind to you see daylight then go back 20 thousanths' lol...:BangHead::BangHead::BangHead:
