I have an extra head that came with my car when I bought it 5 months ago. I decided to have it pressure checked, ported and polished, which has been done. The valve springs I bought as part of a valve package are too high. The Isky valve springs for the Alpine are the same height. My machinist says they are too high by about a quarter inch. The new valves fit fine and are the same size as the old ones that were removed.
The spark plug holes are different than on my series 5. They are not tube shaped but are more oblong. I can get the proper valve springs but my concern is if the stock springs don't fit, will the head bolt to the block okay. Are there any Rootes aluminum heads that will not fit on the block?
I have the casting number, 1980981, but don't know where to cross reference it.
Any ideas?
Thanks,
Murray
