Jim,

I'm leaning towards the late Rover heads with porting and slightly larger valves. I found a company in the UK that offers CNC porting on Rover heads for a reasonable price, so I've asked them for flow numbers, Perhaps we will have some more insight soon.

Sounds good. I think that's the way I'd go provided the flow numbers are as expected.

Greg,

I was told by TA that they are on backorder, but that they do plan on getting them in. My guess is they are waiting until they get enough people "on the list" before they make more.

I think TRS probably still has some and depending on the exchange rate they may not be too dear. My guess would be that TA will order another casting run when TRS re-orders or possibly before if there is enough demand.

Jim,

The TRS heads are showing as $5,900 AUD, which works out to about $4,000 USD (assuming I'm comparing apples to apples): [triumphroverspares.com.au] The TA heads are quoted as $2,900 (USD) assembled. Both are the unported prices, without shipping. So, I *think* the TA heads are the better deal, at least if you're in the USA.

I think you are right Eric. No doubt there will be some who can justify the extra cost. May not be MG owners...
