What do you do?

Nice job

Different collets on the intake and exhaust valves?

How close do you run the springs to Coil bind?

Very nice flow numbers

Thanks, I used a .050 short keeper on the intakes. I think it was .100 from coil bind.

You mention Al Mathon in an earlier post. He was the go to guy and arguably the best for cast-iron repair and welding.

Al’s welding magic was on some of the top pro stock, modified eliminator, and super stock cars. This is back when you had to run the factory cast-iron heads like the old 461, 461x and the 292 turbo heads.

Back in the 70s and early 80s before NHRA went to 500 inches for the pro stock cars, Al was bringing the decks down to 9” for racers running big block Chevy’s.
This was quite an accomplishment back before the flood of aftermarket parts available for the BBC.
Mentioning him it brought back some good memories.
