motor identification help please!!

[bitchin85]

i bought an 85 lwb c10 with a reman 355 in it. its not the original motor so i ran the vin 14010207 and came up with a 83 350 2 or 4 bolt. is there any other way to tell if its a 4 bolt other then droppin the pan? my other question is if the heads are stock. i dont have the numbers off them yet but it has a marking on the front that looks like this...


can someone tell me if they flow good or if theyrejunk? i plan on doin a mean cam with a carb and dual pane intake soon and wondered if they are good or crap.. thankyou

you might need to be more specific
about the head mark

the only SBC poduction heads that have decsent flow are vortecs in my opinion. Edelbrock RPM, Dart PRO1, are good heads and you got more intake choices than vortecs.

i followed the link and it had nothing with that marking. can someone tell me what kind of heads they are and if theyre any good? thankyou

There junk you will spend more money trying to make them flow than just buying a good set of aftermarket heads. putting 305 heads on a 350 puts you in the 10 to 1 range, the valves are small, exhaust flow numbers are really bad

[bitchin85]

so theyre junk 305 heads?
