8 port head for 1275 GT Appendix K

kvalmatch · Post by **kvalmatch** » Thu Jan 11, 2018 8:48 am

Is it correct that it's not possible to use the Arden 8 port head in a 1275 GT Appendix K race car? It's only the Weslake type that is approved?

Never come across any reference to any alternative heads being allowed other than a 12g940

I mean for period G cars (1966 to 1971). I know that the Cooper S is homologated with both 8 port heads, but I only find the Weslake type homologated for the 1275 GT.

Dont know if its built to app k spec; but the Swift built 1275GT Longman race car replica can be seen on the Kent Cams stand at the Autosport Show now on at the NEC.

What's your source?

The FIA homologation papers.

I didn't think heads on Gp 5 racers post '66 over here required homologation as they were free?

The homologation papers in the main site for 1275 GT has C-AEG612 listed as a variation for Gp 2 from 1971. Is that the Arden or Westlake type?

That makes sense. I was thinking of Group 1 regs initially.

For some strange reason, the GT is only homologated with the Weslake.

Yes, it’s strange. And it’s a pity.
