If they need repair, send them back to Brodix....They do the best repair on these heads , hands down...

Pretty common for the Brodix Neal heads to get hairline cranks in the chamber from the plug over to the EX seat - This is espc common on turbo engines for some reason and it never hurts anything to just leave them alone - but I've never seen them crack under the seat insert....

Thats gonna be alot of $$$ to repair with cutting the old seats out, welding, cutting new seat pockets and pressing in new seats, valve job ect.....

Its hard to say for sure how well the repair would hold up since they are ported - I'm sure there isn't a ton of metal in the bowl...

My guess would be that since the crack hasn't made it's way thru to the water jacket yet, the repair if done right would hold up as good as the orginal casting holds out.

Don't hAve a clue were to go from here it has a nice sheet metal manifold and from what bichoff told me nothing fits a neal head stuff Guess I'll wait 5 weeks for new castings. I'm dying to go turbo if I could find a complete topend may just go that route and go turbo. Thanks for the input

a the neal heads were made for individual port injection runner type manifolds I built sixteen / twenty of them for various sprint cars a back when they first came out........BF-200 .....BF-201most of the carb guys would have someone make a sheet metal intake manifold anyways...
