My girlfriend's mom when I was a kid had a '92 white on blue 5.0 bone stock Stang and it was tons of fun. A 650 moves plenty of air for a small block and there is no limit to jetting options. Looks like a really fun project!
Hi Charlie. I have a set of the early aluminum svo heads and on those the bowl was under cut below the seat. It was like there was core shift with the bowl. They need a larger valve just to get rid of the lip under the seat. Thanks for the videos. Andrew
I just finished up a set of y302 ford motorsports heads i picked up with same valves the big difference on these are the egr ports which I will be welding up the thermocouple ports at end of ports and in back of bowl my heads look like these now without the exaust port but my shrt sides are different more like the gt40p I broke my sonic meter and got cautious once I got to exaust ports I finished intakes and chambers . On chambers I cut with using DV area radius rule and his chamber mods especially on ex I also angle milled 030 off heads bringing chambers back to 62 after all cutting was done only thing it makes the vein in chamber a little more pronounced wit a smaller radius at edge I don't have a flow bench anymore so manometer it was and worked great calculations came out @ 280 @.600 int and and 214 at 300 ex but went backwards after not bad but back to 200 by .600
I wonder if all those sharp edges are to stop reversion, cause it looks to me like that port would flow just as well in reverse as normal without them.
I can't think of a good head made and sold by Ford for the Windsor small blocks for street applications. Did they make one that I can't remember? It's crazy how much better the aftermarket heads perform for these motors in comparison to factory parts, including the stuff only available through Ford's performance parts program.
Hi Charlie, it sounds like it has extra cc's..😬 The saying goes, dont dig any further because you cant get the flow back without going back to where you were, however What do you think if you open the port up a bit more, could it eventually wake up? I mean opening the port to a maybe oval shape or something and not touching the bowls? Just thinking its a X -head haha 😂 -juhana
@@servediocylinderheadsLast night i grinded the radiuses with a 3/4 burr on each corner of the 302 port and made the walls accordingly. The port became about 15cc bigger, but i didnt test it. I wonder what would happen if the port was epoxied or the corners filled with clay? - juhana
@@servediocylinderheadsI broke my first grinder today if we dont count the drills. It was a cheap Vevor machine and a piece between the axles that fell apart. I was practicing grinding all 4 ports into an oval shape. Lunch break is over, gotta go continue grinding the iron! 😂 -juhana
@@servediocylinderheadsDroplet? I have seen a small port entry and a large valve flow fast/a lot on a flowbench. Anyway i posted pictures of a different shaped oval port on my UA-cam page.. I dont know if its the best shape for a low port head without epoxy, but it looks pretty 😂 -juhana
Noob mistake....ALL of the sharp edges on the combustion chamber edge plane will cause detonation....they have to blended slightly to reduce high temp heating.
I spray the dykem at max lift the heads will probably run at with the flowbench on.The blue shows where the heavier fuel droplets would flow. Is it perfect? No but with some work the pattern can be made wider and finer. Thanks

Every set of GT40P heads I've ever seen had this same issue. No way to fix it unless you go to a bigger valve.

@@vinmandich7756 That is great. 280 is very good for this style head.
I run a set on a ford lightning.
In for info.

@@pres589 These are dated no doubt. Thanks
Well a lot of folks went pretty fast back in the day with the J302 heads... js
1st!.......Can chamber mods apply to cast iron heads?

whats the function of the blue just kinda sprayed on that little part of the bowl and seat?

@@servediocylinderheads you spray it with flow going through the port?
@@futten3230 Yes
@@servediocylinderheads wow i really thought the fuel spray woulda been more spread out then that
@@futten3230 It isn't fuel but I think it tells you where the heavier particles want to flow. Straight! Thanks
Could you explain the chamber shape to us?
@@joelmclaughlin2558 Relieved to promote flow in a swirling motion for street torque. Thanks
@servediocylinderheads Thanks!
@joelmclaughlin2558 You are welcome.
Ugly. Thank God i don't do the GT thing.
