Great video. Don’t listen to the nay sayers who don’t have the balls to take on a mild port clean up like this. Definitely an improvement over what was factory. Anyone can see that even without flow numbers.
Badass! Nice work. Dig that shop made valve spring compressor. I made mine out of a c-clamp and it works but I will toss it and make one like yours. Fkn love it!!
Haha now one that will work in an early twin cam dyna in frame! I want get the early race springs out of the heads since I got rid of the tw6h cam set for fueling 525's
So what improvement did this work yield? Was there any before/after flow numbers or before/after dyno numbers? If there is no quantification of the work performed then it would be totally useless! Not to be disrespectful because it looks like a nice cleanup job and fresh valve lap. Do you get any noticeable improvement with this work?
Of course there was an improvement ! A guy in his garage can go in with a sandpaper roll & improve the flow to a stock head ! As for flow numbers you only get that when you pay someone a huge pile of cash ! Quantification WTF !
@@leonardstanford1877 if a guy knows wtf he is doing he may get some improvement. Or he could cause flow interruptions and slow down port velocity. Most garage hacks don’t know shyt about fluid dynamics. Oops that engineering nomenclature may be too much for you! 😂😂😂
Kinda completely agree when I’ve built heads on 4cl rice burners I found the guys who just die grinder the hell out of the ports damaged the heads surface finish on intake vs exhaust was important and if you took too much out the combustion area you’d effect the compression of the pistons you’d just spent ££ on
Вопрос) учитывая, что все вытачивается вручную и на глаз, как можно убедиться в том, что обе головы будут иметь один и тот же объём, и пропускная способность будет идентичная? Я нуб, просто интересуюсь. Видел в штатах они на станках все протачивают, максимально идентично.
Wanna know why your combustion chambers ar3 all carboned up? Poor combustion from poor quench distance. Set your quench distance to 0.040” and enjoy better combustion efficiency and cleaner chambers/pistons....
Not exactly proficient. It's easy to take a Dremel to metal and hog out what you feel is in the way, bigger isn't better. I was hoping there would be a little more understanding/tutorial than just showing people how to hog out a head
