Looks pretty good. I am working on a set of magnum heads. I was shocked at the giant guide bosses. They were the first thing I worked on. They look like they were designed by a Ford spy trying to sabotage the competition!

Свечи надо тоже правильно ставить в 8-клапанном моторе. Стоят все по разному. Открытым пространством к впускному клапану - дает больше крутящего момента на низах. К выпускному - на верхах. Открытым пространством вниз - самое неудачное положение. Пламя распространяется где-то с угла и не успевает разгореться по максимуму в нужный момент. Поэтомум либо открытым пространством наверх или боковое расположение. Его можно регулировать толщиной шайбы, если у купленного комплекта свечей лучшее положение не удается найти у всех цилиндров.

I have a set of 302 I just cleaned up the stock casting. I also cleaned up casting flash in the shrouding around the valves, I see now I should angle them back thank you. suscribed to see future progress.

It’s funny I was like totally clueless and home ported a set of heads for my 318. They were closed chamber 273 heads and I cut the chamber to unshroud the valves, cut down the valve guide, gasket matched to a 340 gasket and put 1.88/1.6 valves in it. So basically everything you recommended lol

I’ve been working on some 302’s. Sleeved and looking to run 8mm magnum valves. 1.92/1.625 Even if it doesn’t need a 1.92 that will give me more curtain at any given lift.

Some things are not obvious out the gate....seems like you're on the right track now...because you proved it on a bench.. subbed🤘

Great video! How did the 714 heads turn out ?

My 302 heads 2 inch inlet , 1.55 exhaust

Thanks for the tips! 3:55 valve shrouding is worse than a GM Vortec but those are also shrouded, I deshrouded the same as you on my 906 Vortec

🚒👍

Another good job and you are right what you are saying but did you try back cutting the valves anyway even though that wasn't the problem ? 👍👍

Nice work! I'm reading forum posts saying early casting 318 blocks, or later casting truck blocks that are said to have thicker walls can be bored to 340 bore, 4.04" do you know if this is true? have you done it? I'd love to build a budget 340

Im porting 675’s for my 390 build. Any idea what kind of flow numbers are possible?

What percentage of your valves are your throats.. There's a reason why bigger valves didn't show improvement, if the throats are stock and you added bigger valves There's a restriction..

Your shop is full of toys

This is where the flow bench lies to you. Unshrouding that intake does nothing good for you. With that low flow gasket matching and widening the pinch point are counterproductive as well. Pitot tubes show you where material can come out.
