Does anyone know about or maybe even built a 4 cylinder chevy (pontiac), heads, will late model small block chevy head(s) work on the 2.5L motors? If this works won't this change sides for the exhaust and/or intake?

That usta be a common practice in midget racing when the Iron Duke was a heavy hitter,involved welding the bolt holes in the block and redrilling em for the new head and no it won't change the intake or header sides but it was expensive. Call
Joe Fontana of Fontana racing engines his head may be a bolt on 310-538-2505

THANKS

Thanks for the input. Wouldn't that look good in my 1915 track T
