I would seriously consider buying a used set of nicer aftermarket heads. For probably less than $1000. Think AFR, Trick Flow, etc.
I bought some pro comp junk heads with the same mindset you had and it bit me in the buttocks.
The intake ports were so far they were horrible. I wouldn’t use them and sold them for a $200 loss and moved on and bought new Trick Flow 11rs.
I promise you, save a few extra pennies and skip the temptation to by the $600 eBay heads.
Don’t ask me how I know.
Used sets of heads come up often for around $1000. Sometime less.
Search the bejeezers out of the inter web.
