New SBC heads

[F-BIRD'88]

I'd let it set overnight... Can't believe you carved right thru the pushrod pinch already.. At least if there is a area that is easy to repair its the pinch area in the intake port. ,(stays cool when running)The biggest skill is keeping stuff even.. On iron heads I found a hand flat file helps a lot for keeping the walls straight. It actually cuts pretty fast...
I trust you have long shank cutters for reaching in deep to carve the bowl around the guide boss.
You can cut the (long) shank cutters a bit shorter for stability in the die grinder.

I always do the port flange opening LAST.. As we all are tempted to (over) work that area as its (Too) easy to get at.

Take your time. Take frequent breaks ( its not a race )
Its when you get fatigued that you tend to make mistakes. Nothing done well gets done in a hurry.

Funny on how that was the only port that did that but the new Splash Zone took care of that problem real quick. I like the had file deal, I may try that on the next head. I am just cleaning these up like the Iron Darts I have and then off to the bench to see how much difference there are between the ral and fake Darts.

Welcome, his combo sounds bad azz. Any picture of the head work you'd like to share? 9.80's is movin.

I dont know if he took any pics of the work on them or not.I know he filled floors with epoxy and angle milled them hard.The engine is together in his car so not much to see now.

He is 17 yrs old.My brothers all kind of pitched in and gave him left over junk that laying around the shops.He won the heads in a raffle type deal .Its just used stuff.Sprintcar roller cam and offset lifters.Put port plates on exhaust side for better headers.

I really like those throw together deals especially when they run quick

2nd head I did today went much better using the mini-belt sander to grind the pinch open. Worked very well.

That sounds cool, do you have a picture of the mini belt sander in action?

No I don't but this is one I used with a 36 grit belt from 3M.

Wonder if Binford Tools. (Tool Time) has one with a gas powered chain saw motor.

Is that an attachment that goes on a typical electric angle grinder?
