    Do not take a dremel/die grinder to anything unless you actually know what you're doing, the amount of corrective work I've had to do over the years for people who tought porting or even just a cleanup was a simple exercise is huge.

    If you don't know what you're doing, don't touch it.

    I have to disagree. You'd never learn anything by taking that approach. There was plenty of times that people brought their cars in whilst I was doing my mechanics apprenticeship because they broke it whilst trying to service it themselves. I'd hardly take the stance that they shouldn't try if they don't know what they're doing.
    Rather, don't you think it's better to say that you should ensure that you're well informed before attempting any work of any sort on your car instead?

    Unless you have someone who has experience specifically with 4A-GE heads standing over your shoulder and instructing you, or you're extremely good with CFD and can translate that into a CNC or hand ported head I can almost guarantee you'll get it wrong.

    Every single head that anyone's ever brought me and decided to port themselves has flowed significantly worse than standard on the bench without exception.

    Also if someone can't work on their own car without breaking it I wouldn't encourage them either, definitely don't want their badly repaired cars sharing the road with others.

    As I've never had mine flow tested before and after, I have no leg to stand on for self porting the heads and since you obv have experience above mine I'll just take your word for it. I have removed the suggestion from my post.
    As for your general attitude towards self learning, well, we'll just have to agree to disagree.

    Fuck this stay in your lane idea, its an 86, its a blank canvas for mods inside and out to me. You gotta try or youll never learn. You can even make a flow bench if need be.
