got an lt1 cam over winter and a set of rebuilt 083 head witch i think all slap on with a thin head gasket, any side notes? before i start yanking the l03 apart
also looking for some to burn me a hit or miss chip after thats done
and thos are my plans come summer

 

BTW, my plans before i got the red iroc, i was planing on a 350 TBI build for my blue one, but now my vortec blocks going in the red one now, some other day for the blue one

 

Bump

 

Id just use a regular OEM replacement head gasket. Itll seal better then any sort of shim type.

 

i did think about that but my comp will be low, i will be runing the 083 heads,

 

Might be worthwhile selling the 083s and getting a set of 305 heads. A set of 081's or a set of 305 S/R torkers would work better then trying to use a shim type head gasket to get the CR up.

 

I respectfully disagree but it's only my opinion that you ignore the compression ratio and go for quench. The thiner the head gasket the better the quench in a normal street built engine that has the piston "in the hole". I've always had better succuess with the metal shim gaskets when the engine block and heads had been decked by a reputable shop. If not then the oem will cover more imperfections. The compression ratio should have been thought out before hand and for that reason you might want to look at different heads. Maybe some stock vortec heads if you're building up just a healthy tire roaster.

 

just kinda stumbiled upon the heads, wish they where the 081's
the 803 are rebuilt ready to slap on....

 

Save up for better , just my

Just some info to chew on.............

 

You are doing about the same thing i am, except i am switch intake manifolds and adding a carb

 

Thats what I was eluding to. With an old set of heads and block the possiblity of leaks becomes an issue. Thinner head gaskets may be good but if they dont seal then not much else matters.
