I don't think so...should be 083's, IIRC...I'd have to dig my old heads out to be sure, but I'm almost positive 191's are not it.

mortec.com just has them listed as 87-up 350, so they could be.

Heads

191's and 193's are Lo5 Caprice and truck heads.

1083 (or 083 ) is the L98 head.

14101083 were the casting numbers off my L98 heads. I memorized the number lol. Those are just truck heads as far as I can see. I never remember seeing those numbers pulled off Cast Iron L98's.

Dyno Don is right.

Avoid these heads! They're a bad design (for performance at least).
