Hey Joe, You need the casting # off the block it might be a roller engine they had them in your year but really need the #, You do have a decent set of 64cc heads though.JMO

Look behind the distributer where the bellhousing meets the block there is a flat place on the block # should be there.

the serial number is actaully 14093638 gm 350 block made from 86'-95', my research shows that they made it in both 2bolt and 4bolt mains, and that it had a 1 piece rear main seal, but the wierd thing is that i show that it was made with both flat lifters and hyd roller lifters. i didn't know that gm did this, i guess the only way to really tell would be to pull the inake off and take a look at the lifters them selves, i'm sorry i couldn't actaully give you an answer

Hippie won the prize!

BTW, my spelling is terrible, which is why I am not a writer.

7.2"+/- is standard for a factory roller cam in a sbc.

oh crap i completely over looked that part of the original post. if you have "7.180" push rods they should really be 7.195" for an OE roller, but there is your answer right there, cause std length flat tappit pushrods are 7.800" so you have a roller block/valve train
