What the average cost to have valve seats installed

[mcgrath]

I'm working on a mild stroker project and have a spare eta cylinder head. I can do most of the work on the head to make it flow like a i head but I don't have the ability to install the larger valves like in the i head.
I was wanting to know what it might cost me to have all of the seats replaced in the eta head with ones for the i?

Get an I head....

AFAIK the valves are the same size. But even porting the shit out of the eta head it still wont flow as good as a stock i head.

"i" valves are +2mm over "e" valves

Thats is why it wont flow as good as the i head. I'm wanting to use the eta head because the bottom end is also an eta. I don't want to lower the compression or put in custom pistons. I'm still looking for an idea of cost to have seats replaced. I wouldn't need them cut or anthing just installed.

Depends on which E valves you have. Pre 12/86 they are 2mm smaller (40/34), but after 12/86 they are the same as I valves (42/36).

The head is dated 86 I never measured them. I will go check it out!

well looks like its pre 12/86 they measure 40/34 :(
