Thread: Pro Topline 220cc Iron Lightning Heads

Tweet

I have two brand new bare Pro Topline 220cc Iron Lightning heads for sale. Pro # 223200020A. They were for a 383 that's not going to happen. 72cc chambers. Right about 9.6:1 CR with flat tops. Can handle up to .700 lift with the right springs and valves. These are too big for a putt around town 350. Should be used with an Edelbrock 2975 Victor Jr. Flow specs on these heads are:
.400 Int 249.84 Ex 176.85
.500 Int 264.62 Ex 186.34
.600 Int 272.23 Ex 190.13
.700 Int 282.08 Ex 194.87

Int.2.02" Ex 1.60", 3 angle valve job, drilled for 7/16 rocker studs, phosphor bronze exhaust guides, manganeze bronze intake guides.

Pro Topline has been bought by Comp Cams and these are getting scarce while the line is temporarily shut down. When production resumes, it is to be expected that the price will jump.

Price? I have a 383 that's a little anemic with smog heads, am interested in something that will flow better.

Biff,
