$2,000 firm - New Edelbrock Victor Jr. heads for small block Chevy with full portwork by Mondello. Never bolted on an engine.

Modified Offenhauser 4-carb intake port matched to heads included at no additional charge. Intake is similar in layout to Man-A-Fre and is 95% completed.

If interested, please send PM. I can send photos of heads and intake (zip files) via E-mail.

I am located NW of Houston, Texas. Will ship parts within lower 48 states and split cost of shipping...... Payment by US Postal Money Order accepted.

If picking up parts locally, cash on receipt...... No checks, MOs nor credit cards if picking up locally.

All sales are final......

I had Mondello rework these 23 degree heads for a 427 stroker small block as an affordable alternative to 18 degree or 15 degree heads.

I asked Mondello to port these heads so as to maximize flow at valve lifts below 0.550". I was looking for a flow rate for this engine of at least 300 cfm at that lift.

The specs Mondello gave me are as follows......

* Edelbrock Victor Jr. Aluminum Heads Fully Ported By Mondello Racing - 23 degree with standard valve spacing (no offset rockers required)

* 65cc Combustion Chambers, polished

* 2.08" intake X 1.60" exhaust valve sizes - Stainless Steel Pro-Flo with 5-angle valve job

* Intake Ports - 2.35" High X 1.40" Wide = 3.25 sq. in. cross section at port opening (allowing for rounded corners) - Pushrod pinch point measures 2.80 sq. in.

* Exhaust Ports - 1.65" High X 1.65" Wide = 2.68 sq. in. cross section at port opening (allowing for rounded corners)

* Dual Valve Springs Set @ 140 lb. seat pressure / 340 lb. open / cryogenic stress relieved

* P.C. Teflon Valve Guide Seals

Flow @ 28 in. (no pipe)

LIFT - INTAKE - EXHAUST
0.100" - 071.00 - 063.00
0.200" - 145.00 - 113.00
0.300" - 205.00 - 157.00
0.400" - 260.00 - 190.00
0.500" -306.00 - 205.00
0.550" -313.00 - 211.00
0.600" - 320.00 - 217.00


Following portwork and machining, Mondello cryogenically treated these heads
