Info wanted on Indy LA X heads

gzig5 said

Your question referenced X heads for a street build. Not that you had a set of X heads breathed on by a well regarded builder in Ed Hamburger. Big difference and puts your question in a completely different context, so you can understand my confusion. Again, comparing apples to watermelons. So to the original question, I would definitely say the LA-X is still an improvement over the original X-heads and a good choice for a steel headed street build. Probably not an improvement over the modified set you have.

I went to look at them and decided they are not for me. I have many X heads here ported and stock. The ports on these Indy x heads would need work compared to what I already have and the compression would be to high for my existing short block

They are still listed if any of you are interested. Mopar Indy X Heads

Just look like a down grade from what we already have. I want to use everything that was under my hood except the block and heads for the new street car. It was a fresh 416 and I thought I would use it all instead of buying everything again. We have many engines and parts just never had Indy X heads. Sorry for asking or offending those who have them. I think The factory ported X heads will work just fine for me.
