Closed Deck EJ20 Base Shortblock With Forged Internals Breather Caps and Fittings Head Diameter (mm) 33mmThis closed deck block design has been proven to withstand extreme boost levels resulting in high cylinder pressures without the worry of cracking a sleeve. The billet material that reinforces the combustion area has been further optimized with our V3 closed deck block in the known problem areas making it a far superior product to any sleeved block.
