ultra pro sc1 heads??
1 - 4 of 4 Posts
This is a pair of Don Losito Ultra-Pro Ford SC1 heads that have been CNC lightened & fully ported with Titanium 2.180" x 5/16" intake & 11/32" x 1.600" exhaust valves from Xceldyne, and they have Xceldyne ultra-light steel retainers (much more stable that titanium at same weight) with titanium locks & Isky Tool Room springs.
A ported 2932 Edelbrock/RYR intake is included and so are the A1 12-point head studs (for Dart block) plus T&D shaft rockers with solid bars and 1.7 intake, 1.65 exhaust ratios with special tapered 7/16" pushrods. The heads have some nice CNC milling work done to them and non-offset lifters were used with those pushrods on a 9.200" deck block.
These were just pulled off a 390 CID World of Outlaws Late Model engine built by Pro-Power Racing Engines in WI. The engine was purchased from Darren Miller, and he claimed the engine was freshened with new parts 300 laps ago by Pro Power & he claimed Pro Power made 830 HP and 630 TQ with it. The engine was not raced after it was bought from Darren due to a class rule change that only allowed a Spec Brodix head.

Losito makes some very nice heads, have used servel over the years. As far as nitrous head, if the champer has a good layed back shape I would say yes, if not they need a little work in the champers. Also look at the springs, for what is used on roundie engines isn't alway good for straight line racing.
Overall most SC1 heads are bad ass!
