Found it. Whoever ported these heads went too far in the exhaust port in the area of the guide. Pinhole about .030 right into a water passage. If it were on the dragster it would get Devconned and called good. Not for this usage though.Effer obviously didn't understand that that area is almost a dead zone that doesn't need anything other than a smoothing. Oh well,new  bare castings with guides are only $2400. Add pistons at around a grand and this little bit of experience will run around $4K.   5: 5: 1:  Everything has a silver lining though, a few minutes more it would have been a lot more $$$$. BTDT too many times to count.

Amazing what a little hole can cost............ or I've drilled wells for less than finding this water cost.......................or that little thing costs HOW MUCH?.................... or fill in any sarcastic comment feels appropriate.   LMAO LMAO

I'll probably send both heads off to Brodix for sonic thickness probing of all ports to see if they should be welded or scrapped for new castings.

A few more minutes was all it had left at that point. The pinhole thing happens with ported heads. No casting is ever perfect especially in the water jackets. Port work is always a leap of faith. The hole could due to overall lack of port wall thickness in the area or just be from an errant grain of sand when cast. Brodix will have the right answer for me but I'm leaning towards new castings with less port work done. The heads were on an alky outlaw sprint car in their former life. I bought them used. Brodix does basic hand port work on these heads at their factory. They are not sold in an as cast state. I don't  know if more port work had been done to them. Ironically,I had the same issue except in an intake port on my other set of radically ported heads on dragster. These heads flow approx. 400cfm intake/240cfm exhaust right out of the box with well over 425cfm intake/275cfm exhaust fully ported. There are only a few SBC heads that flow even close to those numbers. They make serious HP.

those impressive number for sure i was just wondering if these were the same heads you had used on the motor in the past w\o issue. i know that motor has sat a while.  i know! that motor makes some damn good bottom end tq for grunting when needed. so before that little mis hap how was it running on the sand?  the pin hole sucks but the pistons are pretty concerning. are those je pistons forged pistons?

Heads are likely 10 years or more old. I cannot blame former owner for selling a known bad set.. I don't believe he knew of this  since they have held water and been brought to operating temps many times since .

yes,forged. I agree the pistons are more of a concern. I'll have JE place the ring package further from the top on replacements.

just wondered if you had been running them or purchased for this build.        the je pistons....are they 2618 or 4032 alloy?

 THese pistons and heads are not used for anything other than maximum effort engines. SFAIK there are no options for the slugs concerning alloy unless something changed in the last couple years.I doubt anything has changed though.

Looks like they made a bad try at installing the valve guide sleeves.   Busted out the boss when bored and drove in the bronze sleeve.  That thin sleeve should have been blended back to the boss area.  Sleeves are not made to run out in the open. 

If I believe I cannot do something it makes me incapable of doing it. But when I believe that I can, then I acquire the ability to do it , even if I didn't have it at the beginning.
