1.94/1.5 valves.. these heads worth ne thing

[89SilverBullet]

Alrite.. well i was curious so i decided to run the numbers on th heads i have sittin in my shed this is wat mortec.com says they are

14102193...87-up...305/350......1.94"/1.5" valves


these heads anything special? i know they are the big valve heads.. but would they be good for a 383 build or anything at all? or they just 2 paperweights with some big vlaves?

also the block i have sitting in my shed is a

14093638...350...87-95...2 or 4...Roller or flat tappet cam, one-piece rear seal

ne thing special or just a reglar standard 350 fuel injected block?

THe 193's are just stock 87-up heads, they all have the 1.94/1.5 valves. if you were to get them rebuilt and a little port job on them it would be almost worth it to spend a little more and get some of the vortec heads from Summit or Scoggin-Dickey, or some cheaper aluminum heads. You'll get more out of them then the stockers, so nothing special. THe block would be a good block though (thats what im using), ecspecailly if its 4 bolt.

alrite i didnt know about the heads... i knew they were big vlave heads but didnt know if they were not as common or w.e..

and no my block is only a 2 bolt..

it will be a 383 someday.. its already bored .30 over just sititn ehre ready for that eagle stroker kit.

Yea my block is also a 2 bolt main but yuou can always buy those 4-bolt conversion caps, then get it aligned bored, or you could also install a main cap girdle. It helps keep the caps form blowing apart but a 2-bolt will handle quite a bit of horsepower though. Will your engine be N/A or will you have nitrous/supercharger/turbo?

for the amount of work it would take to get those heads flowing well i'd just buy some vortec's or sr torquer's. sell your old ones to someone with a cracked head and make some money back.
