I'm putting together a .030 over 350 chevy. The short block was a put together some time ago by someone else. (I received it by bartering parts) the pistons are cast dished with small valve reliefs and seem to displace around 11-12cc in the dish by my measurements. I measured the deck height and the piston is quite deep about .035 under the block deck.
I'm putting a pair of summit vortecs on it that have 67cc chambers.
The camshaft is the Lunati Voodoo #VDSC-262 its 220 intake @ .050 and 227 exh @ .050 lobe separation is 112 the lift is 468/489
My concern is this, because the pistons are so deep I'm not sure i'll have adequate compression for the cam if I run a standard head gasket. I'd like to use a standard gasket because the block was never decked. I think they may be more forgiving but I'm not sure that's a fact.
A steel shim gasket (by my math) puts me right in the sweet spot for compression but i'm concerned about how well they will seal as i have not personally decked the head or block. Though they look good with a strait edge.
Do you all have any input toward what would be the best head gasket to run in this application.
Thanks in advance for your opinions.
