Good job there! did you cnc milled the combustion chambres, or was that done with a hand-tool? if cnc milled, how did you get the shape exactly the same? (some kind of digitalizing proces like that 'centroid porting' thing?)

@bartjooh

Hey thx for the comments. No all freehand porting. Has been my job for 25 years now so ive had my fair share of repairs.

@Xceldyne Would you be able to do that with cast iron cylinder heads? I know I know, most guys just junk the cast heads once they crack, but I have a numbers matching vehicle in which I need to keep numbers matching, and I can't find a head to replace it anywhere. If you did the cast iron, what technique would you use, weld, or braze? Thanks for any info you can share in advance...

few blow holes there old boy need to spice up youre torch work abit. what did the engine swallow, was it just another tuning fuckup??? heads look too sweet to have dickheads tuning it fucking it if so !!!!

[smithsil]

looks great but did those changes have any effect on the CR of the engine? I'd be concerned about pre-ignition or detonation? Any issues there?

Looks like your filler metal was a different alloy(?)
