- What's the stock '96 L31 Compression ratio? thinking on using 0.026" compressed inch head gaskets to bump the compression a bit
- Will this Compression Ratio good for the LT4 Cam?
Not sure what will be the CR with this heads
- Im between AFR0912's 190cc or Edelbrock 60975 170cc E-tecs (we won't be using the stock heads anymore)
AFR has bigger valves but might be overkill with the stock intake and 19lb poppets. Is it worth to swap heads with this alum versions?
All of this will be coupled with a Vigilante 10.5 3600 stalll and 1 5/8 Long tube headers and 1.6 Roller Rockers on 3.42 gears
quench is about .026, with -12cc vortec heads, stock compression is like 8.9 or low 9's, ill be using felpro 1094 on my build using a vortec block and rotating assembly with a 68cc 083 head milled out.
