    I’ve seen pictures of SBC and Y-block on early fours. Lots of machining required I’m sure.

    Bill Stipe, of sumthin or other engineering did a SBC on an A, now makes lumpy cams for T's, still in business I think. Glad I could be so helpful! Someone here will know more

    We have some really nice reproduction heads available that are designed for the A/B and now Burtz engines. Look up the new Miller or Serr cylinder heads. $5k only sounds like a lot up front, there are a lot of half done projects out there that have 1000’s of hours invested.

    Ever since all engines went to main journals between every cylinder, evenly spaced cylinder bores are the norm. The Model A/B motor requires about an extra inch between 2 and 3 that no late model head can span. Bill Stipe cut his chebby head in half and made a spacer to line up the bores. The average Joe rarely makes it beyond cutting the head in half. Expect that hiring a cast iron welder to put the head together will cost about $2-3k. I have seen a few attempts at using a pair of Subaru heads… these save the cutting in half step, but never seen one run

    Right now you can buy a brand new Riley 4 Port out of the original patterns and bolt it on. How could you even think of a small block chevy head.

    I know this car had used a "small block chev" head although I think it maybe a chev LS head.

    I do know they originally ran a gemsa 4 port and could not get near the record, and after changing the head to the chev head that they set the current record.
