I had wanted to use factory iron heads for my 403 build, so I purchased a set of #5 for a really fair price, with the intentions of building them up. I had contacted Jim @ J&S Machine about a Stage 1 buildup. His price was $1200 for what I wanted, but shipping iron heads both ways is not cheap. An alternative was use a set of #4 he had, and use his commercial account to ship just (1) time. I have verbally agreed to this, but he is taking his time, and not being very responsive with an ETA. Granted he has relocated and "retired" to Florida, but he agreed to build the heads. Without me asking - he has stated he would send me pics of the heads, along with an ETA on (3) occasions. That has not happened. So this morning I messaged him, and asked for the pics, along with valve & spring specs. Although he always responds, the story was the same... "I'll let you know on Sunday".
So now I am seriously considering another alternative. ProComp aluminum heads from Olds Rocket Parts. The fact that these heads are readily available, not to mention the weight savings- (which you know I am a fan of), has me wondering what you guys think? This may not matter to some of you guys, but it does to me... you know how the paint ALWAYS burns off the exhaust ports on Olds iron heads, and looks like crap? This will not happen with the aluminum heads - no paint to burn off. The price difference is $49. I bet the shipping is cheaper also.
