Yes, it really is! I am going to submit this to our shop secretary. If they dont approve it I will get back with you on where the Industrial supply place you guys use.? ThanksMoparman1972 wrote:$731 is RIDICULOUS!!!!!
Look around. We ordered a tube of the right diameter from an industrial catalog and cut it to size. You should be able to build it for around $50.
Yeah me too Dylan Thats the way they came. Nick a seat and I'll have to 'sink' the seat to start over and you know about how wedge heads flow with a lower seat?Moparman1972 wrote:In a perfect world, I do the valve job after the porting. Then there's no worries, unless I am a complete hack! Which I am sometimes....
With my luck it would be a huge 'fissure' BTW, Dylan what would you and your father suggest to protect those seats? I was pretty nervous working 'backwards like that. I checked the runout and width of the valve job. It was 'spot' on and I would really like to keep it that way. We have a new Serdi Seat and valve guide machine on order, but for now all we have to 'work with' are ancient grinding stones, that are all wore out and used up.Moparman1972 wrote:Neglegible unless it was quite a nick!
Thanks Dylan!! I would love to see those ports. I re-thought the 'mods' bit after we talked. With this flow bench at my disposal I would be a fool not to try and gain flow. If I ruin a head so be it. I can buy a single head or re-weld it up. Either way no pain no gain!! I have to keep reminding myself that I only have 4.220 fixture. We are having 4.375 and 4.500 fixture made for us out of poly carbonate plastic but until I get my greedy paws on them this is what I have to work with so the flow is defintely shrouded and skews my results. But I'll post Thur. results as soon as I get home from shop.Moparman1972 wrote:Aha! I gotcha now Eddie, thanks for the pics.
My father finished another set of heads the other night, and in addition to a wedge on the shortside radius he has a splitter blending the protruding valve guide in. The splitter was only a couple CFM improvement over just the shortside wedge when flowed. Almost not worth the time, and the port got pretty crowded for trying to shape both. Car heads would be a nightmare to try to do this on.
I still can't find my damn camera, but I will post pictures of this soon. I also found pictures of a set of Chevy 350 heads he did back in '92, I will try to scan these at work.
Eddie I have fingers crossed for big improvements for you! (If it doesn't work out, I imagine I will have to go into witness protection for sinking so much of your time.)
