Witch would be better I got a buddy who has the 416 and think he has the 081's said that he would give me eather witch will be stronger? But for free eather will work right???

 

both i think from what ive read in the last week have almost equal flow potential when ported im not sure bout stock....but what do u have now center bolt valve covers/heads or perimeter cause if u go from one to the other your intake wont bolt up so id stay w/ what kind of heads u got as far as that part goes if both r free

 

Right now I have the stock 305 heads on a 92 rs and i do have the center bolt valve covrs so if i swap for eather the intake wont line up is that what you are saying????

 

the 081's are tpi 305 heads and are the ones you want. they have the later designed (86up)72* angle center two bolts while the 416's have the traditional 90* angle center two bolts.(this is what he was referring to about the intake not bolting up) they also have provisions for your centerbolt valve covers and the 416's are perimeter mount valve covers.

now, i'm looking for some 416's. you think your buddy would give them to me?

 

I have '93 RS and put the 416's on. I would not do it again. Go for the 081's. It matches up with your intake. It also matches up with an Edelbrock Performer TBI intake if you want to put one on later. The 416's will not be a direct bolt on.

 

mw66nova he was going to give me them because he owed me some money but i'll sell them to you if you want to pay shipping lol

 

i'm going to be up in OH at the end of the month. we need to swing by youngstown and could swing by your place in TN on the way back (would be the first week of Oct.) pm me with a price and i'll consider buying them from you.

 

Just to note as well, they are the exact same head design (runner, exhaust).. they just have the different intake and valve cover bolts as mentioned above.

 

I believe a few of the first '88 LO3 cars had 416 heads and some of the last of the '92 cars had 081 heads. These are very rare though since 99% of all LO3's had the 187's.

 

HA found a set guy wants like 150$ is it to much??? And what would be a good cam for this set up. I read where shifty said with a set of good flowing heads that the LT1 would not be a good choice any ideas????????

 

I only said that if you have the valve guides cut down on those heads to accept a larger lift cam. Otherwise the LT1 cam is great for those heads. $150 is a bit steep.

 

Oh I'm sry I might of read it the wrong way But thanks for your help

 

a '93 RS bill? coulda sworn that purple monster thas a 92... lol

 

It is. Fat fingers.

 

lol, i blame it on microsoft... its easier that way....
