need to sell my 243's first unfortunately. I have the cam for these heads.

I currently have T&D's on my 243's, will these still work on the ETP's?

very interested.

what size are the combustion chambers?

T&D's will most certainly work on these heads. The combustion chambers are 65cc.

Yes in all theory, there are a few checks I'd do, but nothing major. These are coming with the pushrods and should be very close as the block I have was never decked, but for good measure, I'd check valve wipe and lifter pre load just to be on the safe side. Everything should be plug and play with more air flow and velocity and not to mention added PTV clearance!

Due to the lack of interest (and funds getting tight) I am keeping these heads and using them.
