well im supose to be buying some 305h/o heads this sunday and i was wondering if anyone knew how to find out whatthe casting numbers are?so i dont screw myself over..
like a link to a website er anything would be helpfull.

this would be greatly aprecieated.

 

Head Casting Number Guide
Scroll down to the lower half of the page.
#14014416, 14022601 (1980-85) perimeter valve cover bolts.
#14102187 (1987-91) center bolt valve covers.
All are 58cc combustion chamber, so keep in mind you'll be bumping up your compression ratio.

 

thanks alot your a big help.
and im really diggin that 1st gen. its done up reall nice! =)
been using google to find sumthing on it but not even close.

 

Are the 187 ones the swirl port heads?

 

Whoops, yes they are. Stick with the first two. The 187 heads won't breathe well in the higher rpm range.

 

For others, the web site is mortec.com for engine & head identification.

 

ok thanks for that quick call on the 187 heads.
i dont want them i would basicly end up with what i got then except small cc.

but thanks for the help everyone it is greatly apreceated
