DESCRIPTION:
Edelbrock E-Tec 170 cylinder heads are designed for street/high performance use on 302, 327, 350, and 400 c.i.d. Small block
Chevrolet engines using Vortec style manifolds. E-Tec 200 cylinder heads are high-end street and racing cylinder heads intended for large
displacement small block Chevrolet engines. Both of these heads feature 64cc combustion chambers. Complete cylinder heads come assembled with
valvetrain parts capable of operating up to 6500 rpm.
Higher rpm applications will require the use of suitable valvetrain parts, such as larger
valve springs and retainers
. Other outstanding features include phosphor-bronze valve guides, ductile iron valve seats and premium one-piece,
stainless steel, high-flow valves, heat-treated machined steel retainers and valve locks, rocker studs, 5/16” guide plates, and heavy duty valve springs
which work with cams having valve lifts up to .600”. Spring load at .600” lift is 340 lbs. Check camshaft manufacturer’s spring load specifications
when using other than Edelbrock camshafts. These powerful heads use the
stock Vortec location for intake and exhaust flanges and bolt holes
,
and centerbolt valve cover rails for compatibility with original equipment and aftermarket parts. Bolt holes for exhaust and intake flanges and rocker
studs are fitted with helicoil inserts for increased strength.
